Protex Safe FD-4020K Extra Large Depository Safe
Protex FD-4020K Depository Safe for Commercial and Agency Use
The Protex FD-4020K is a depository safe built for supermarkets, cash-handling back offices, fuel stations and multi-shift operations where each shift drops a till bag that only a manager or an armoured-carrier route can remove. Protex Safe has manufactured this class of unit since 1991 from its plant in Irwindale, California, and every figure on this page is taken from Protex's own published specification for the FD-4020K rather than estimated.

Where the FD-4020K is used
This depository safe suits supermarkets, cash-handling back offices, fuel stations and multi-shift operations where each shift drops a till bag that only a manager or an armoured-carrier route can remove. The pattern it solves is simple: reduce the amount of cash, keys or sensitive paperwork sitting in the open during a shift, without giving every member of staff access to what has already been deposited. Separating the person who deposits from the person who can open the unit is the control that matters, and it is the reason this class of product is specified in retail loss-prevention and agency property procedures.
Installation and anchoring
At 245 Lbs this unit should be anchored. Protex supplies anchoring hardware and pre-drilled holes on units in this range. Anchor into concrete, masonry or structural timber — fixing into plasterboard alone defeats the purpose. For wall and floor models, confirm stud spacing, cavity depth or slab thickness before the install date, because a return for the wrong body depth is the most expensive mistake on these orders.
Buying for an agency, school or multi-site rollout
Security Pro USA supplies federal, state, local and commercial buyers, and can quote against a purchase order. For rollouts across multiple sites we can confirm keying arrangements, freight to each location and realistic lead time before you commit. Request a quote with the model number (FD-4020K) and the number of units, and we will come back with pricing, availability and delivery. Volume, agency and reseller pricing is quoted rather than listed.

Frequently asked questions
What are the exterior dimensions of the Protex FD-4020K?
The Protex FD-4020K measures 20” (W) x 40” (H) x 20” (D) externally, with an interior of (inner compartment) 19-3/4” (W) x 8” (H) x 14-1/2" (D). Measure your opening against the exterior figure before ordering.
How much will the Protex FD-4020K hold?
Usable capacity is 5.12 cubic inches. For cash handling that is normally quoted in envelopes or till bags per shift rather than volume, so tell us your drop volume and we will confirm the right model.
How thick is the steel on the FD-4020K?
Protex specifies a door thickness of 2-1/2" (1/2” solid steel plate). Thickness is the single best indicator of pry resistance on this class of unit.
Does the Protex FD-4020K need to be anchored?
At 245 Lbs the unit is light enough to be carried away unanchored, so Protex supplies pre-drilled anchor holes and hardware. Anchoring into concrete or structural timber is strongly recommended for any cash-handling install.
What lock does the FD-4020K use?
Door thickness inter compartment 3/16" Drill resistant hard-plate Spring-loaded re-locker 1. If you need a different lock format across a multi-site rollout, ask us before ordering — keying and lock options vary by model.
Can we buy the Protex FD-4020K on a purchase order or agency terms?
Yes. Security Pro USA sells to federal, state, local and commercial buyers and can quote against a purchase order, including multi-unit and multi-site rollouts. Request a quote and we will confirm current pricing, lead time and freight.
