Right-Hand Mortise Entry Lockset

The Tuff Stuff 510026AR is a heavy-duty mortise lockset finished in Satin Chrome 26D. It is designed for right-hand doors in commercial or residential entryways. The unit includes a solid brass cylinder and two keys for immediate security.

Check Door Handing and Backset

Verify that the door swings to the right from the exterior before ordering. Confirm the existing mortise pocket can accept a 2-1/2" backset and a front face plate measuring 1-1/16" x 7-5/8". Ensure the cylinder-on-outside and thumb-turn-on-inside orientation matches your requirement.

Replaces Comparable Commercial Mortise Sets

This lockset replaces worn or outdated commercial mortise hardware such as the Marks 91A/26D equivalent. The jump is worth it when the original cylinder is compromised or the spindle mechanism fails. Solid brass construction and surface-mounted knob plates restore reliable daily operation.
