The adjustable part of the chute slides into the fixed chute allowing for varied wall thicknesses. You then secure the adjustable chute to the wall (screws not included) and we suggest adding adhesive glue to seal and secure this portion of the chute. Please note this drop box is not designed to be in the out doors. The exterior chute must be installed under cover of an eave or large over hang. The exterior chute is not water tight and must be installed under cover.

This drop box is now available with either the key lock or electronic keypad lock.
