Vision Panel Lockers

Vision panel lockers put a clear window in every door, so a supervisor can see whether a compartment is occupied — or what is in it — without carrying a key. We stock the Probe Vision Panel Metric range: fifteen listings covering 1, 2, 3, 4 and 6 compartments per column, in 300 mm single width and in a wide format at 380 and 450 mm, with flat or sloping tops. Every unit is 1800 mm full height, cold-rolled mild steel, powder-coated, and fitted with a Type A cam lock on each compartment.

The thing worth knowing before you compare prices

This is the only single-column locker in the catalogue that isn't a charging locker. We checked all 67 Probe lockers we list. Every Standard Metric, Standard Imperial and Perforated locker is a double-width or triple-width nest — two or three columns joined into one bank. The only single-column units are the ten 300 mm Vision Panel lockers on this page and the PowerBox charging range.

The practical consequence: if you need one narrow column of lockers — beside a doorway, in a corridor recess, at the end of a bench run — a solid-door locker in that footprint is not something we can supply. Your single-column option has a window in it. That is worth knowing at survey stage rather than at quotation, and it is the reason this range answers a question the rest of the locker estate cannot.

The wide-format listings are also single column — the extra size is depth and width, not a second column. So every one of the fifteen products here occupies one column of floor.

What the range actually covers

Five door counts, three listing formats, fifteen products:

Compartments per column	300 mm flat top	300 mm sloping top	Wide format (380/450 mm)
1 door	Yes	Yes	Yes
2 door	Yes	Yes	Yes
3 door	Yes	Yes	Yes
4 door	Yes	Yes	Yes
6 door	Yes	Yes	Yes

There is no 5-door, 8-door, 10-door or 16-door vision panel locker. The density ceiling on this range is six compartments per column. If you are specifying a high-density scheme — a school corridor at eight or ten compartments per column, say — you are choosing between a solid Standard Metric or Standard Imperial nest and losing the window, or accepting six per column and taking more wall. Our 8-door and 10-door pages show what the solid ranges offer at those counts.

The whole range is metric. Every one of the fifteen states 1800 mm; the string 1780 appears nowhere in the range. There is no imperial vision panel locker. If you are matching an existing 1780 mm imperial installation, a vision panel unit will stand 20 mm proud at the top of the run — see the height and depth notes on our imperial page before you mix ranges.

The sloping top is a flat £24.77, and on a 1-door that is the worst deal in the range

A sloping top stops people stacking boxes, sitting or climbing on a locker bank, and stops dust collecting. It is priced as a flat fee per column, not a percentage — and this range proves it more comprehensively than any other page on the site, because every unit here is exactly one column and the range spans five door counts and six sizes.

We compared every flat/sloping pair at matched door count, width and depth. Thirty matched pairs. Every one is £24.76 to £24.78. The fee does not move with compartment count, it does not move with depth, and it does not move with width.

Because the fee is fixed and the compartment count is not, what you pay per compartment for a sloping top varies six-fold:

Configuration	Flat top, 300 × 300 mm	Sloping top	Premium	Per compartment
1 door	£324.04	£348.80	£24.76 (7.6%)	£24.76
2 door	£369.17	£393.94	£24.77 (6.7%)	£12.38
3 door	£393.98	£418.76	£24.78 (6.3%)	£8.26
4 door	£417.88	£442.66	£24.78 (5.9%)	£6.20
6 door	£505.60	£530.38	£24.78 (4.9%)	£4.13

On a 6-door column the sloping top costs £4.13 per compartment and is an easy yes. On a 1-door it costs £24.76 for one compartment — 7.6% of the whole locker — and is the weakest sloping-top buy anywhere in our range. If you are placing single-door units where nothing will be stacked on them, take the flat top and spend the difference on depth.

The same £24.77-per-column figure holds across our flat-top and sloping-top collections, where it appears as £49.54 on a double-width bank and £74.31 on a triple — two and three columns of the same fee.

Depth pricing is incoherent — and on one product 70 mm of depth costs 94 pence

This is the part of the range worth reading twice, because the price steps do not behave and a buyer sizing by percentage will get it wrong.

Each 300 mm listing offers three depths: 300, 380 and 450 mm. Here is what each step actually costs, flat top:

Door count	300 mm	380 mm	450 mm	First step	Second step
1 door	£324.04	£338.90	£363.68	+£14.86	+£24.78
2 door	£369.17	£379.09	£398.44	+£9.92	+£19.35
3 door	£393.98	£428.23	£438.19	+£34.25	+£9.96
4 door	£417.88	£455.53	£456.47	+£37.65	+£0.94
6 door	£505.60	£506.69	£533.56	+£1.09	+£26.87

On the 4-door, going from 380 mm deep to 450 mm costs 94 pence — while the previous 80 mm of depth on the same product cost £37.65. That is a fortyfold difference between two adjacent steps on one listing. On the 6-door it runs the other way: the first step is £1.09 and the second is £26.87.

Two pieces of buying advice fall straight out of that, and neither is guesswork:

• On the 4-door 300 mm locker, always take the 450 mm depth. It is 50% more usable volume per compartment for less than a pound.
• On the 6-door 300 mm locker, take the 380 mm depth — £1.09 for 27% more volume — and think hard before paying £26.87 for the last 70 mm.

The general rule: price the depth you want against the depth immediately below it, on that exact listing. There is no percentage that describes this range.

Wide format: on the 3- and 4-door, width costs less than depth

The wide-format listings move the compartment out to 380 or 450 mm wide as well as deep, and bundle both tops into a single listing with six size-and-top combinations. Compared like for like at 380 mm deep, flat top, the step from 300 mm wide to 380 mm wide costs:

Door count	300 × 380 mm	380 × 380 mm	Cost of the extra width
1 door	£338.90	£366.91	+£28.01 (8.3%)
2 door	£379.09	£407.03	+£27.94 (7.4%)
3 door	£428.23	£442.28	+£14.05 (3.3%)
4 door	£455.53	£465.19	+£9.66 (2.1%)
6 door	£506.69	£537.54	+£30.85 (6.1%)

On the 3-door and 4-door, widening the compartment is cheaper than deepening it was — £14.05 and £9.66 against the £34.25 and £37.65 those same products charge for their first depth step. For anything bulky and shallow — a coiled hi-vis, a hard hat, a folded coat — width is the better-value dimension on those two configurations. On the 1-, 2- and 6-door it is the dearer one. There is no consistent answer; check the two numbers on the door count you are buying.

The wide-format range tops out at 450 × 450 mm. The dearest unit in the whole range is the 6-door wide format, sloping, 450 × 450 at £585.22; the cheapest is the 1-door 300 × 300 flat top at £324.04.

Cost per compartment

Vision panel lockers are single-column units, so the cost per compartment is high compared with a multi-column nest — that is the trade you are making for a one-column footprint and a window. At the entry size, 300 × 300 mm, flat top:

Configuration	Price	Cost per compartment
1 door	£324.04	£324.04
2 door	£369.17	£184.59
3 door	£393.98	£131.33
4 door	£417.88	£104.47
6 door	£505.60	£84.27

A 3.8× spread across one page, and the whole of it is the door count. The carcass, the steel, the finish and the lock are the same in every row — a 1-door locker is one big compartment in the same 1800 mm box that the 6-door divides into six.

For comparison, a Standard Metric 10-door double-width nest works out at roughly £52.89 per compartment and a 6-door triple at around £56.53. If cost per locked compartment is the driver and you have the wall for it, a multi-column nest is materially cheaper. Buy vision panel for the visibility and the single-column footprint, not for the unit economics.

Specification, verified across all fifteen

Every claim below was checked against all fifteen product records, not inferred from one:

• Height — 1800 mm, full height, on all fifteen.
• Construction — cold-rolled mild steel, powder-coated, on all fifteen. The word "welded" appears nowhere in the range; these bodies are formed, not welded.
• The panel — reinforced acrylic in a powder-coated steel surround, stated on all fifteen. Not glass and not polycarbonate — neither word appears anywhere in the range.
• Doors — reinforced for rigidity and ventilated, on all fifteen.
• Lock — Type A cam lock, one per compartment, on all fifteen. There is no hasp, padlock, coin-return or electronic option on any of them — those words appear zero times across the range. If key administration is a concern, our guide to locker locks sets out how to run a keyed scheme.
• Colour — three carcass colours (silver/grey, black, white) and seven door colours (red, yellow, blue, green, black, white, silver) — 21 combinations, and the price is identical across all 21 at a given size. Colour is free. That is why the 300 mm listings carry 63 variants (3 sizes × 21) and the wide-format listings carry 126 (6 size-and-top combinations × 21).
• Manufacture — Probe, UK, on all fifteen.

What the product data does not state

Published as a gap rather than filled in with an assumption. Across all fifteen listings there is no warranty period, no lead time, no stock status, and no steel gauge or sheet thickness. Get all four in writing at quotation. We also do not list an antibacterial or antimicrobial coating on this range — some competing vision panel lockers offer one, and if that is a clinical requirement it is not something these listings support.

When a vision panel is the right specification

The window is not decoration. It exists to remove a category of work:

• Lost property and locker audits. Walking a corridor and seeing which compartments are occupied takes minutes; unlocking 60 doors to find out takes an afternoon. On a school locker scheme with end-of-term clear-outs, this is the whole argument.
• Contraband and safeguarding. Visible contents deter what would otherwise be hidden, and make a check non-intrusive.
• Anywhere the locker holds something that must be verifiable at a glance — a charged radio, an issued respirator, a returned set of keys.
• Clinical and cleanroom areas, where visual inspection without contact is preferred.

And when it is the wrong specification: anywhere staff store personal belongings and expect privacy. A window in a staff changing room is a different proposition from a window in a school corridor, and it is worth putting to the workforce before it is ordered. For that use, a solid door from the Standard Metric range or a ventilated perforated door gives airflow without visibility. Our staff and workplace locker guide covers the allocated-versus-daily-use decision that usually settles it.
