Q1: Can it withstand rain? Could I mount it on the wall near the hinges, with the arm connected to the top of a right-swing gate?
A1: Yes. Both models are designed for indoor/outdoor use and are suitable for wet environments. Mounting on the wall near the hinges with the arm connected to the top of the door is a common “top jamb” installation method and works for a right-swing door.
Q2: Does it open more than 90 degrees? I need about 110 degrees.
A2: The D4000 supports a maximum opening angle of 180 degrees, while the D500 supports up to 120 degrees. Both will work if you require about 110 degrees.

Q: Can this be trimmed to fit a 33-3/4" door space? Is the 2" trim the minimum? Will it seal uneven gaps, and what is the maximum gap size it covers?
A: Yes, trimming from 36" down to 33-3/4" is possible. The minimum trim allowance is 2" and must only be cut from the non-plunger end. Do not trim closer than 1-1/2" before the set screw on the plunger side, as that is the mechanical limit. This model is designed to seal uneven door gaps, with a maximum sealing capacity of up to 3/4".
