Position the catch on the door frame where you plan to install it. Make sure the U-bolt is oriented horizontally. Center the catch to the frame so installation screws can be securely installed. Pass the tip of a pencil through each screw hole in the catch to mark their positions on the door frame. Remove the catch.
Install a drill bit with a smaller diameter than the threaded shanks of the installation screws in the latch kit. Drill a pilot hole through each screw-hole mark on the door frame. Remove the bit and install a driving bit in the drill. Reposition the catch on the door frame, aligning the screw holes in the catch with the pilot holes in the door frame. Using the screws provided in the latch kit, screw the catch to the door frame.
Test-fit the hasp portion of the latch on the shed door. The hasp should be horizontal, and the slot in the hasp should fit easily onto the U-bolt in the catch. Mark the positions of the screw holes in the base plate of the hasp on the shed door. Remove the hasp. Drill a pilot hole through each screw-hole mark on the door.
Reposition the hasp on the shed door. Align the screw holes in its base plate with the pilot holes in the door, then screw the base plate to the door.
