Design Hardware DFS-U Universal Dome Floor Stop

Both are covered in the box. The DFS-U dome floor stop ships with a 1-1/2 inch wood screw and plastic anchor for wood subfloor, plus a 1-1/2 inch machine screw and lead anchor for concrete or masonry. That means one part number works whether you're setting stops on a wood-framed corridor or a slab, which is what you want when you're doing a whole building and don't want two SKUs.

The dome stands 1-1/2 inches high and is 1-3/4 inches in diameter at the base. Measure the gap under your door leaf: if the undercut is more than 1-1/2 inches (common where doors run over thick carpet or a return air gap), the door will pass over the stop and it won't do anything. Under that, the dome catches the door face. The 1-3/4 inch footprint also tells you how much floor you're committing to at each opening.

Solid cast brass, not zinc or pot metal. That matters in high-traffic commercial openings where a cast zinc stop cracks at the anchor after enough hits. The finish is plated over the brass casting, so a scuff exposes brass rather than a different base metal.

Three: 613 dark bronze, 626 satin chrome, and 606 satin brass. Those are the three finishes that cover most commercial hardware schedules, 626 to match satin chrome levers and closers, 613 for dark bronze packages, 606 where the door hardware is satin brass. Pick the one that matches your existing lever and hinge finish so the stop doesn't read as an afterthought on the floor.

Yes, a grey rubber bumper is included on the DFS-U, set on a 7/16 inch thick base. The rubber takes the door impact instead of brass hitting the door face, which is what keeps you from denting a hollow metal door or marking a wood one. Nothing separate to order for the bumper.

A dome floor stop like the DFS-U is what you use when there's no wall behind the door swing, the wall behind is glass or a full-height window, or the wall is drywall with no blocking to anchor into. It anchors into the floor instead, wood or concrete. A wall stop is the better choice when there's solid backing at the right height and you don't want anything in the walking path, because a 1-1/2 inch tall dome sitting on the floor is a mop obstacle and, in a corridor, something people notice with their toes. Floor stop for glass fronts and open walls, wall stop where you have a wall to hit.

That's what the DFS-U is set up for. "Universal" here means the fastener pack covers both wood and concrete floors, so a property manager or MRO buyer standardizing a facility can hold one part number in three finishes rather than stocking separate wood-floor and slab versions. The dome shape is non-handed, so it works on left- and right-hand doors without ordering by hand.

It stops the swing only. The DFS-U is a dome stop with a rubber bumper, so it arrests the door at the point you set it and nothing more. If you need the leaf to stay open, that's a holder or a hold-open arm on the closer, a different part. Buyers replacing a stop that had a hook or catch on it should note the DFS-U won't do that job.

Set it where the door face contacts the dome before the lever or panic hardware reaches the wall, so measure the swing first and mark the contact point on the floor. On depth: the supplied screws are 1-1/2 inches, so you need that much sound anchoring material below the finished floor. Thick carpet and pad or a thin topping over a slab eats into that, and on a slab you'll be drilling for the lead anchor with a masonry bit.
