Metro ironmongery: round and square door trim

Locks, cylinder covers, and latch plates make up Metro ironmongery, a corner of this cabinet hardware catalog built for doors instead of cabinets. Rocky Mountain Hardware makes the line from solid forged metal, noticeably heavier than a stamped piece, with every item available in a round shape or a squared one. A house finished entirely in Metro keeps one look running from the entry to a hall bath, rather than switching styles room by room as different doors get updated over time.

Five lock types, five different jobs

• Oval cylinder trim backs a standard cylinder lock, in a length matched to door thickness.
• The bit-key piece fits an old-style skeleton-key mechanism, not a modern lock.
• Latch trim sits over a door's strike and latch hardware, no cylinder involved.
• Bathroom trim handles interior privacy locks.
• Euro profile pieces fit multipoint hardware on patio and entry doors.

Knowing which lock already sits in the door narrows this list to one option long before shape enters the decision. A locksmith or the original door manufacturer can usually confirm the mechanism type if it isn't obvious from looking at the existing trim.

Round versus square, and getting the size right

The round and squared versions of Metro trim do an identical job; picking between them is purely a look, not a function. Sizes stretch from a 57mm round lock plate up to an 89mm by 330mm euro profile piece built for taller multipoint hardware. A trim plate at this scale can't be cut down once it arrives, so confirm the lock and door prep measurements ahead of time; a plate cut for one size won't stretch to cover another. Sticking with one profile for a whole remodel also simplifies reordering later, since a single shape covers whatever comes up as work continues.
