Cylinder Side Mortise Lock PULSAR RAZB16 – round profile, side-mounted cylinder

PULSAR RAZB16 is a round-profile cylinder side mortise lock designed for doors where the cylinder is mounted on the side of the lock case. The mechanism provides mechanical locking when used with a compatible round cylinder (cylinder sold separately). The lock is intended for installation in wooden, metal or composite doors in residential and light commercial settings where a side-mounted round cylinder is required. The design accommodates standard mortise preparation and supports applications such as replacement of existing side-cylinder locks or integration into new door assemblies.

How to use

Install the PULSAR RAZB16 mortise lock into a prepared mortise pocket in the door edge following standard carpentry practices.

Usage recommendations

Choose a round-profile cylinder with the desired security features and length appropriate to door thickness. For exterior doors select cylinders certified for higher security and weather resistance. During replacement projects confirm mortise dimensions and backset compatibility to avoid additional modifications. For best performance, periodically lubricate the cylinder and lock mechanism with a dry lubricant recommended for locks and check mounting screws for tightness.
