Trimco 1240 Hinge Pin Door Stop Stop

Both. The 1240 hinge pin stop is made to work with 1/4 inch and 5/16 inch hinge pins, so it covers the two pin diameters you find on standard commercial butt hinges. It clamps onto the pin itself, so there is no drilling into the door, the floor, or the wall.

There are rubber bumpers on both ends of the 1240, one bearing on the door and one on the frame, so metal never contacts finished surfaces on either side. That matters on painted hollow metal frames and on wood doors where a bare metal stop would leave a witness mark within a few months.

A hinge pin stop like the Trimco 1240 mounts on the hinge pin, so nothing gets drilled into the wall or the floor. That is the reason property managers reach for it on turnover work and in units where you cannot cut into a finished wall or a tile floor. The trade-off: a wall or floor stop takes the impact at the door edge, farther from the pivot, while a hinge pin stop loads the hinge and the frame. Where a door gets slammed hard and often, the more durable choice is a floor stop or a wall bumper. Where you need a no-damage, no-drill fix that still keeps the knob off the drywall, this is it.

The 1240 carries BHMA L02121. That is the finish hardware designation a spec writer or institutional buyer needs on a door hardware schedule, and it is what lets the stop be approved against a hardware set rather than substituted at the last minute.

Commercial. Trimco builds the 1240 as a heavy duty hinge pin stop, and it is catalogued for commercial use rather than as a light residential bumper. For office suites, schools, healthcare corridors, and multi-family common areas it is a legitimate spec, not a hardware store substitute.

No. The 1240 fastens around the hinge pin, so a single door leaf stays hung and the install is a hand tool job at the hinge. That is why it is common on occupied turnover work where you cannot pull the door for an hour. Set the stop at the angle you want within the 70 to 100 degree range as you tighten it down.

The 1240 ships as model 1240619, the 619 satin nickel finish. If your existing hinges and lever trim are satin nickel or brushed chrome tones, it will read as a match on the frame; against bright brass or oil rubbed bronze hardware it will stand out.
