Cylinder Collar Guard 9276
This Marks USA cylinder collar guard is designed for mortise lock installations where cylinder protection is required. It provides a free-spinning ring that prevents forced removal of the lock cylinder using common burglary tools. The guard suits residential and commercial doors fitted with mortise cylinders.
Wrought Brass Construction
The guard is made from wrought brass with a polished brass US3 finish that resists corrosion and matches traditional hardware. Its 5/8" projection adds a low-profile barrier without interfering with door operation. The included insert ensures a secure fit around the cylinder, and the unit is sold as a single guard with the cylinder purchased separately.
Mortise Cylinder Compatibility
This guard fits standard mortise cylinders only and will not suit rim cylinders or other lock types. The free-spinning design protects against gripping tools but does not prevent other forms of attack such as drilling or picking. Buyers needing protection for multiple cylinders must order additional guards.

Questions about this item
What type of cylinder does the 9276-3 collar guard fit?
It is designed for mortise cylinders and includes a free-spinning insert that resists forced unscrewing with tools.
What door projection does the 5/8" high guard add?
The guard extends 5/8 inch from the door surface, so the mortise cylinder must accommodate that additional projection.
How is the guard installed and what step is often missed?
The guard threads onto the mortise cylinder before the cylinder is secured in the lock body; the cylinder itself is sold separately and must be purchased to complete the installation.
