Trimco 1231/1233 Floor Stops

Height is the whole decision with the 1231/1233 floor stops. They come in two: 2 inches and 2-7/8 inches. Measure from the finished floor to the bottom of the door at the point where the stop will sit, then pick the height that puts the bumper against the door face rather than under it. Carpet, thick tile, or a raised threshold eats into that clearance, so measure at the stop location and not at the hinge side. Undersized and the door rides over the stop; oversized and it hits high on the door face.

Yes, the 1231 and 1233 floor stops are ADA compliant. That matters most in corridors and egress paths where a floor-mounted object in the walking surface can become an obstruction, and it is the reason these get specified in schools, healthcare, and government work. They are commercial-rated hardware, not a residential bumper.

A wall stop only works if the door swings into a wall that is solid where the knob lands, and it protects that one spot. A floor stop like the Trimco 1231/1233 takes the impact at the floor, which is what you want when the door opens into a doorway, a corner, a glass wall, a partition with no backing, or anywhere the door would otherwise travel past the wall entirely. The trade is that a floor stop puts a fixed object in the walking surface, so it goes as close to the wall as the door swing allows. These are ADA compliant, which is the reason they get used in occupied corridors.

Cast bronze or brass, solid metal rather than plated zinc or plastic. That is why they show up in commercial and industrial buildings, hospitality, retail, government and military facilities, and offices, where a stamped stop gets flattened or torn out. The casting is the durable part; the finish is what wears cosmetically over time.

Seven finishes, and both heights are offered in every one of them: 605 bright brass, 606 satin brass, 613 oil rubbed bronze, 613E dark oxidized satin bronze, 622 matte black, 625 bright chrome, and 626 satin chrome. Those are standard BHMA finish numbers, so if your existing levers or hinges are marked 626, the 626 stop is the match. Property managers standardizing a building can order both heights in one finish and keep the whole floor consistent.

They are the same cast floor stop family in two heights, 2 inches and 2-7/8 inches, sharing the same finish range. Pick by the clearance under your door, not by model number. For ordering, specify height plus finish, for example 2-7/8 inch in 626 satin chrome.

These are stops, not holders. The 1231/1233 arrests the door's swing to protect the door face and the wall behind it, then the door swings back freely. If you need the door to stay open on its own, you want a floor stop with a hold-open feature or a separate door holder, which is a different part.
