Right-hand mortise entry lockset

The Tuff Stuff 5700AR is a heavy-duty mortise entry lockset finished in polished brass. It suits commercial, institutional, industrial or residential doors that require a right-hand configuration. The lockset uses a 2-3/4" backset with a 1-1/4" x 8" wide faceplate. A solid brass cylinder and two keys are supplied.

Through-bolted screwless installation

Through-bolted mounting secures the lock body without visible surface screws on the knobs. Screwless knobs with self-adjusting spindles simplify alignment during fitting. Installers must prepare a standard mortise pocket for the wide faceplate. Misaligned mortise cuts or incorrect door handing are the typical causes of binding.

Sustained commercial-grade operation

Scissor and anti-friction latches reduce wear during repeated daily cycles. The 1" deadbolt and rocker mechanism maintain positive engagement over long periods. Solid brass components resist corrosion in high-traffic environments. The lockset is not intended for doors that require left-hand or reversible handing.

Questions about this item

How do I confirm the scissor latch and anti-friction latch engage smoothly after installing the 5700AR mortise lockset?

Close the door and turn the knob; the scissor latch should retract quietly and the anti-friction latch should hold the door without rattling, while the 1" deadbolt throws cleanly with the thumb turn or key.

Which components come in the box for the 5700AR and what must be purchased separately?

The box includes the mortise lock body with 1-1/4" x 8" faceplate, screwless brass knobs with self-adjusting spindles, solid brass cylinder and two keys; no additional parts are required for standard installation.

Which handing should I select for a right-hand door using the 5700AR?

Choose the right-hand version listed as 5700AR; it is factory-configured for right-hand doors with the cylinder outside and thumb turn inside.
