Right-Hand Mortise Entry Lockset

The Marks Metro 114A/26D is a mortise lockset designed for right-hand entry doors. It features a satin chrome finish and a solid brass cylinder supplied with two keys. The unit is keyed different and uses thru-bolted knobs for secure attachment. It suits commercial or residential entrances needing a durable mortise mechanism.

Thru-Bolted Knobs and 1-Inch Deadbolt

Thru-bolted knob mounting distributes force across the door thickness for added strength. A one-inch deadbolt throw engages the strike for reliable locking. The front face plate measures 1-1/16 by 7-5/8 inches and fits standard mortise preparations. Cylinder operation on the outside pairs with an interior thumb turn for convenient egress.

Replaces Cylindrical Sets on Prepped Doors

This lockset upgrades doors already cut for a 2-1/2 inch backset mortise pocket. It is not suited for tubular latch cut-outs or left-hand door swings without modification. The jump is worth it when the existing prep matches the 16 face plate and the project demands commercial-grade brass cylinder security.

Questions about this item

How is the thru-bolted knob assembly mounted on a 2-1/2" backset mortise door?

Insert the mortise case into the pocket, align the spindle, then fasten the through-bolts from the interior rose through the case to the exterior knob — the bolts draw both sides tight without exposed screws.

What cylinder maintenance is required for the solid brass keyway over time?

Lubricate the solid brass cylinder annually with dry graphite; avoid oil-based sprays that attract dust and cause the pins to bind.

Which component reaches its limit first during repeated heavy-duty entrance cycles?

The 1" deadbolt throw and latch bolt absorb the primary impact; their engagement surfaces wear before the through-bolted trim or cylinder mechanism.
