What this lock is and who it fits

This heavy-duty mortise lockset uses a 2-1/2 inch backset and a solid brass 5-pin cylinder supplied with two keys. The storeroom function keeps the outside lever always locked, requiring a key for every entry, while the inside lever remains free for egress. It is built for commercial or residential doors prepared for the Marks Metro 116DW or 114DW series.

Limits of the storeroom function and prep

The latch-only design omits a deadbolt and rocker, so the lock cannot secure the door independently of the strike. Operation depends on a cylinder on the exterior only, with no interior thumb turn, which means the door cannot be locked or unlocked from inside. The left-hand orientation is fixed and cannot be reversed in the field.

What it replaces and when the swap makes sense

This set fits the same door preparation as Marks Metro 116DW and 114DW mortise locksets, allowing a direct retrofit without new mortise cuts. The screwless, thru-bolted lever plates and independent spring-loaded spindles upgrade the trim durability on existing doors. The change is worthwhile when the current hardware is worn, when a keyed-different cylinder is required, or when ADA-compliant lever trim is specified.

Questions about this item

Is the 2-1/2" backset the right choice for my door prep?

The 2-1/2" backset matches standard commercial mortise preparations and fits the same cut-out as Marks Metro 116DW and 114DW locksets.

What does "Storeroom" function mean for daily use?

The outside lever is always locked and requires a key; the inside lever always retracts the latch for free egress — no thumb turn is present.

How does the thru-bolted, screwless lever design affect installation?

Plates bolt through the door with captivated spindles and lever support springs, giving a rigid, ADA-compliant fit without exposed screws on the trim.
