This kit is easy to install - the cam slides on the drive shaft, and the limit installs in pre-drilled holes. It is also easy to adjust by turning the cam until the limit is in the desired position and tighten the screw. Because of its simple and effective design, the kit is totally reliable - it is impossible for the carriage door opener to physically miss its limit.

Please note that two kits are needed for dual carriage door openers.
