Locking Hatch for Work & Job-Site Trailers
External access without unlocking the whole trailer.
Mount a locking hatch on your work, contractor, or mobile-workshop trailer to reach generators, compressors, or stored tools from outside — without opening the rear doors. Perfect for job sites and mobile workshops.
Popular DIY Uses
- Power cords out to the job site while the trailer stays locked
- Compressor air hose pass-through
- Generator cord routing
- Quick access to fasteners and small tools
Which size? Contractors often run two or three openings — the keyed-alike Small 2-Pack or 3-Pack keeps one key for every hatch.

Work Trailers — FAQ
Can I run a generator inside the trailer and pass the cord through the hatch?
+
Never run a generator inside an enclosed space. Keep the generator outside or in a properly vented compartment built to the generator maker’s instructions, and use the hatch only to pass the cord.
Which size should I buy?
+
Both rectangular doors use a 4-7/8" wide opening. The Small door needs a 5-1/8" tall opening; the Large door needs a 6" tall opening for a little more room to reach in or pass bulkier plugs and fittings. If you want more than one opening, the Small 2-Pack and 3-Pack are keyed alike.
What tools do I need?
+
A drill, a jigsaw or oscillating multi-tool (or a step bit and nibbler for sheet metal), a tape measure, exterior-grade sealant, and the right screws for your wall. Print our true-scale template so the cut lands exactly right.
