Hettich SS D3 Right Prolock Infinity Main Door Safety Lock (Both Side Movable)
Overview
The Hettich SS D3 Right Prolock Infinity is a main door locking solution that combines a mortise lock and a night latch system in one unit. It is built in stainless steel and designed for residential and office main doors that require both high security and everyday convenience, with handles that move on both sides of the door.
