Sdc CYL-6KDQ 6-pin Mortise Cylinder Cross Collar

Product Description

The SDC - SECURITY DOOR CONTROLS CYL-6KDQ is a 6-pin mortise cylinder with cross collar designed for use in commercial and institutional door hardware assemblies. Mortise cylinders are the industry standard for heavy-duty locksets installed in steel and wood mortise lock bodies. The CYL-6KDQ features a 1.125-inch format and a cross collar configuration that secures the cylinder within the mortise lock body, preventing rotation under torque. Licensed locksmiths and commercial door hardware installers are the primary trades working with this component.

This cylinder is suited for commercial door applications where mortise locksets are specified, including office buildings, schools, healthcare facilities, and multi-unit residential properties. The 6-pin tumbler configuration provides a higher pick resistance than 5-pin cylinders and is compatible with keying systems that require larger key change combinations. It is sold as a single unit.

Key Features

• 6-pin tumbler configuration for increased security and greater key combination depth
• Cross collar design locks the cylinder in place within the mortise lock body
• 1.125-inch cylinder length suited for standard mortise lock profiles
• Single-unit packaging for individual replacement or new installation
• Designed for commercial-grade door hardware assemblies

Compatibility

Designed as an OEM-style replacement or upgrade cylinder for commercial mortise locksets that accept a standard 1.125-inch 6-pin mortise cylinder with cross collar format.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician. Secure the door in its open position and disengage the lockset before removing or installing the cylinder. The cross collar must be properly seated and the retaining screw fully tightened to prevent cylinder rotation during operation. Refer to the mortise lock body manufacturer specifications for cylinder retention hardware torque and alignment requirements.
