It gives you a lockable pass-through for cords, hoses, and air lines, or quick outside access to something stored inside — without opening the main door. Q: What size hole do I cut for a LockingHatch? A: Small door: 4-7/8" wide × 5-1/8" tall opening (bezel 7-1/4" × 6-7/8"). Large door: 4-7/8" wide × 6" tall opening (bezel 7-1/8" × 8-1/8"). Use the free printable, true-scale template on the Find My Cutout page. Q: Can I install it myself? A: Yes.

Q: What can I mount a locking hatch on? A: Enclosed and V-nose cargo trailers, landscape and lawn-care trailers, job-site work trailers, truck caps and service bodies, sheds, workshops, garages, carports and pole barns, and mobile-home skirting.
