Trimco 90ST000- Mortise Locks (Stockholm)

Those are the two functions the Stockholm 90ST000 mortise lock is built in, and you pick one at order time. Q10 is the entry function, the usual choice for a unit or office door where the lever is locked and unlocked by key from outside. Q14 is the store door function, used where both levers stay active and the lock is retracted by key from either side, typical of retail and lobby entrances. The function is fixed by the part you order, so decide which behavior the opening needs before you buy.

Yes. The Stockholm lever from Trimco's Urban series is ADA compliant, which is what a lever trim buys you over a knob on an accessible route. That matters on corridor, restroom, and unit doors in occupancies where accessible operation is required.

It is a mortise lock, meaning the door needs a mortise pocket prepped in the edge rather than the two round bores used for a cylindrical lockset. If your existing doors are bored for a cylindrical or tubular lock, this is not a drop-in swap.

Commercial. The Stockholm 90ST000 is a commercial mortise lock, and Trimco lists it for commercial and industrial buildings, government and military facilities, hospitality, multifamily and mixed-use, and office buildings. It is not a residential-grade bored lock.

Stainless steel. The Urban series levers, Stockholm included, are manufactured from stainless steel, which is why Trimco points them at high-rise condo, multifamily, and office traffic rather than light residential duty.

That is the intent of the Urban series. Stockholm is one design within it, and Trimco offers multiple styles in the family so you can keep one lever program across a property while varying the look between, say, unit doors and amenity spaces. All of the Urban levers are ADA compliant, so switching styles does not change accessible operation.
