Why a Rim Lock for Outdoor Gates?

Rim locks surface-mount on the door — no need to cut a mortise or modify the door frame. That makes the SK-NT4 ideal for retrofitting iron gates, aluminum doors and existing wooden doors where drilling into the frame is difficult. The IP66 rating means it works year-round in rain, sun and dust.
