Sloping-Top Lockers

This collection holds 32 sloping-top Probe locker configurations, from a single-door vision panel unit at £348.80 to a ten-door triple-width imperial nest at £2,120.17. All are full height — 1800 mm on the metric, PowerBox, vision panel and perforated ranges, and 1780 mm on Standard Imperial, cold-rolled mild steel with a powder-coated finish, UK manufactured by Probe, and fitted with a Type A cam lock as standard.

A height difference that is not in the product names and matters for a mixed run: the Standard Imperial lockers are 1780 mm tall, not 1800 mm. All 19 imperial products in the catalogue state 1780; all 48 metric, PowerBox, vision panel and perforated products state 1800. So metric and imperial nests differ by 20 mm in height as well as 5–7 mm in depth — a mixed run will not line up at the top or sit flush at the face. The imperial body exists to drop into an existing 1780 mm installation without re-planning the wall; if you are not matching one, specify metric.

The sloping top is a small feature that solves a specific problem: an angled top stops users leaving bags, litter and coffee cups on the bay, keeps dust off, and discourages people sitting or climbing on the lockers. That is why it is specified in schools, changing rooms, food areas and healthcare settings. If you want a usable flat surface on top, or the lowest overall height under a window or a low ceiling, go to flat-top lockers instead — everything else on this page applies equally to both.

Corrections to what this page previously said

We check our own copy against the live product data, and this page did not survive that check. Three claims have been removed because the specifications on all 32 products do not support them:

• Locking. The page offered "cam, hasp, coin-return or electronic locking". Across all 32 product specifications, "cam lock" appears 96 times and "hasp", "coin" and "electronic" appear zero times each. What is actually specified is a Type A cam lock, fitted as standard. If you need hasp, coin-return, master-keyed or electronic locking, ask us — do not assume it from this page. Our guide to locker lock types explains the options that exist in the market.
• Construction. The page said each nest is "welded from sheet steel". "Sheet steel" and "welded" both appear zero times in the product data. The specification says cold-rolled mild steel — 88 occurrences — with a powder-coated finish.
• Door types. The page offered "solid or perforated doors" and omitted the third range entirely. There are three door types here: solid (Standard), laser-cut perforated for airflow, and vision panel.

We would rather publish the correction than leave a specification on the page that the product data contradicts.

The size trap: metric and imperial are 5 to 7 mm apart

The size selector on these lockers offers twelve width × depth options, and they are really six sizes specified twice — once metric, once imperial:

Metric	Imperial	Difference
300 × 300 mm	305 × 305 mm	5 mm
300 × 380 mm	305 × 381 mm	5 / 1 mm
300 × 450 mm	305 × 457 mm	5 / 7 mm
380 × 380 mm	381 × 381 mm	1 mm
380 × 450 mm	381 × 457 mm	1 / 7 mm
450 × 450 mm	457 × 457 mm	7 mm

Those differences look trivial on a single locker and are not trivial on a run. Ten 457 mm imperial nests are 70 mm wider than ten 450 mm metric nests — enough to lose a wall recess, foul a door frame or leave a gap at the end of a bay. And you cannot mix metric and imperial nests in one run and get a flush face; the fronts will step.

The practical rule: if you are extending or matching an existing installation, find out which system it was built in before you order. If you are starting fresh, read on, because the choice is not neutral on price.

Imperial costs more than metric — on every comparable pair

Comparing like with like — same door count, same number of columns, same top — imperial is dearer than metric every time:

Configuration	Metric from	Imperial from	Premium
10 door, triple width	£1,695.92	£2,020.25	+£324.33 (19.1%)
8 door, triple width	£1,396.93	£1,661.46	+£264.53 (18.9%)
6 door, triple width	£1,064.95	£1,263.08	+£198.13 (18.6%)
5 door, triple width	£992.59	£1,099.76	+£107.17 (10.8%)
8 door, double width	£973.13	£1,054.74	+£81.61 (8.4%)
10 door, double width	£1,261.90	£1,318.99	+£57.09 (4.5%)

Unless you are matching an existing imperial run, specify metric. You are paying between 4.5% and 19% for a difference of one to seven millimetres.

The price floor is the most expensive locker on the page

This collection starts at £348.80. That figure is the single-door vision panel unit — one compartment. Worked out per compartment, it is the dearest thing here by a wide margin, and the pattern behind that is the most useful buying rule on the page.

Configuration	Compartments	From	Per compartment
Standard Metric, 10 door, double width (300 mm)	20	£1,107.42	£55.37
Standard Metric, 8 door, triple width	24	£1,396.93	£58.21
Perforated Metric, 6 door, triple width	18	£1,114.49	£61.92
Standard Imperial, 10 door, triple width	30	£2,020.25	£67.34
Vision Panel, 6 door, 300 mm	6	£530.38	£88.40
Standard Imperial, 2 door, triple width	6	£889.85	£148.31
Vision Panel, 1 door, 300 mm	1	£348.80	£348.80

The cheapest storage in this collection costs £55.37 a compartment and the most expensive costs £348.80 — a factor of more than six, on lockers made of the same steel to the same height. What separates them is almost entirely how many compartments share one carcass, one top and one delivery.

So the rule is: buy the largest nest the wall will take. Doors are comparatively cheap; carcasses are not. A single-door locker is the right answer when you genuinely need one locker in one place — and it is an expensive way to buy six.

Median rates by range, for orientation: Standard Metric £59.16 · Perforated £61.92 · Standard Imperial £70.53 · PowerBox charging £111.58 · Vision Panel £139.59 per compartment.

Choosing the door type

Solid steel doors are the default: maximum privacy, maximum security, nothing visible from outside. They are also the cheapest per compartment.

Perforated doors are laser-cut for constant airflow through every compartment. The carcass and floor stay full solid steel and only the doors are perforated, and the doors are reinforced to keep their rigidity despite the pattern. This is the right specification for wet or damp kit — used PPE, gym and swimming kit, wet weather gear — anywhere contents need to dry between uses. Sports facilities, pools, fire stations and industrial PPE drying are the named applications. On a per-compartment basis the ventilation costs very little: £61.92 against £59.16 for solid.

Vision panel doors let staff see whether a compartment is occupied and what is in it, without opening it. That matters where lockers are audited, where contraband is a concern, or in schools. They are only offered here in the 300 mm single-width format, 1 to 6 doors, which is why they carry the highest per-compartment rate in the collection — it is the format, not the glass, that costs the money.

Charging lockers: the cheapest way to add mains is to buy it with the USB

The PowerBox range puts charging inside the compartment. The price ladder is not what most buyers expect, and it produces a clear recommendation.

Doors	3-pin UK mains only	USB-A + USB-C only	Mains + USB
16	£1,083.42	£1,686.25	£1,795.39
10	£863.72	£1,115.76	£1,189.27

USB costs far more than mains — £602.83 more at 16 doors and £252.04 more at 10. But once you have committed to USB, adding 3-pin mains on top costs only £109.14 at 16 doors and £73.51 at 10 — around 6 to 7% on the order. If USB is on your specification, the combined unit is close to a rounding error and it future-proofs the bank against whatever connector comes next.

The reverse is worth knowing too. If a 3-pin socket alone will do the job, it is remarkably cheap storage: the 16-door 3-pin UK mains unit works out at £67.71 per compartment — less than the Standard Imperial 8-door triple-width nest at £69.23, which charges nothing at all. Separate USB-A and USB-C collections cover the connector split, and the laptop charging lockers buying guide covers device-storage specification properly.

Widths, door counts and how the configurator works

Two numbers describe every nest here. Door count is how many compartments in a column — 1, 2, 3, 4, 5, 6, 8, 10 or 16 — and it sets compartment height within the fixed carcass height. Width is how many columns are joined into one bank: single, double or triple. A 6-door triple-width nest is 6 × 3 = 18 compartments in one structure.

Fewer, taller doors suit full-length coats, bags and outdoor kit. More, shorter doors suit valuables, phones and personal effects and cost less per user. Browse by door count at 6-door, 8-door, 10-door and 16-door.

The colour options explain the variant counts you will see: 3 carcass colours (silver/grey, black, white) × 7 door colours (red, yellow, blue, green, black, white, silver) = 21 combinations, multiplied by the number of sizes offered on that model. That is why one product shows 63 variants (three sizes) and another 126 (six sizes) — it is one locker configured, not 126 lockers.

What the product data does not state

Across all 32 products, the specification does not give a warranty period, a lead time, a stock status, a master-key or suiting option, or a steel gauge. We will not fill those in with numbers we cannot source. Lockers are largely made to order in the configuration and colours you choose, so ask us for a lead time against your actual specification rather than assuming one — and ask before you commit to an installation date.

Planning the room around them

Lockers are half of a changing room. The other half is seating, and the two interact: a bench put directly in front of a locker bank leaves roughly 500 mm of usable standing room once a door is open. Cloakroom benches and our changing room layout guide cover circulation, bench-to-locker ratios and the depths involved.

For specification by setting, see the school lockers, gym and leisure lockers and staff and workplace lockers guides. If you are weighing lockers against a cupboard, steel storage cupboards vs lockers is the comparison. And the general metal lockers buying guide covers tops, sizing and security across the whole range.
