Orca Hardware 3-1/8" Spring Door Stop

It is a baseboard stop. The 3-1/8 inch spring body screws into the baseboard behind the door swing, and the door strikes the tip rather than a floor-mounted bumper. If your baseboard is short, damaged, or you have no baseboard at all behind the swing, go to a floor bumper instead, such as the Delaney 2 inch round solid brass floor bumper.

The 3-1/8 inch length is the overall stop, so the door is held roughly three inches off the baseboard. That clears most knobs but a long lever or a thick escutcheon can still contact the wall. Where you need more standoff, a longer spring stop like the Sure-Loc 3-3/4 inch, or an adjustable baseboard stop such as the Delaney solid brass unit that extends 3-1/2 to 4-1/2 inches, buys you the extra projection.

A spring stop flexes when the door hits it, which is why it is specified for residential openings. On a heavy commercial door or a corridor that sees carts and constant use, a rigid stop takes the abuse better, for example the Sure-Loc 4 inch solid door stop, or the Hager 212 adjustable rigid stop with an 80 to 120 degree range where you also want to control how far the door opens.

The Sure-Loc DS3 is a 3-1/8 inch spring door stop for residential doors, matching the Orca TH-3118 on both the spring stop format and the 3-1/8 inch length. Either one mounts to the baseboard and absorbs the door swing on the coil. The Orca TH-3118 is a zinc alloy body offered in oil-rubbed bronze, satin nickel, polished chrome, and black, so if you are matching an existing finish across a run of units, check the finish first and treat the two as interchangeable on size.

Step up in length. The Sure-Loc DS4 is the same spring door stop style in a 3-3/4 inch length, and the Sure-Loc DS7 is a 4 inch solid door stop if you would rather not use a coil. For a wider reach that you can dial in on site, the Delaney 40201X is a solid brass baseboard door stop adjustable from 3-1/2 to 4-1/2 inches. The Orca TH-3118 is fixed at 3-1/8 inches, so length is the deciding spec here.

Move to a rigid stop. The Sure-Loc DS7 is a 4 inch solid door stop with no coil to flex or take a permanent set, and the Hager 212 is an adjustable rigid door stop with an 80 to 120 degree range, so you can set exactly how far the door opens rather than just cushioning the impact. The Orca TH-3118 is a spring stop, which flexes by design and is the reason it takes abuse in high-traffic openings.

Zinc alloy. That is a cast, plated body rather than solid brass, so it takes the plated finishes well and holds up to normal door traffic. If you want solid brass in a baseboard stop, the Delaney adjustable baseboard stop and the Delaney round floor bumper are both solid brass.

No. The 3118 spring stop is not ADA compliant, so on an accessible route where protruding-object rules apply you need to look at a different mounting style. On the fixtures side that usually means a low floor-mounted bumper rather than a wall stop.

Yes. The Sure-Loc 3-1/8 inch spring door stop is the same size and style, also a residential spring stop. If you are already stocking Sure-Loc, it is the straight cross. Sure-Loc also makes the same stop in 3-3/4 inch if you need more reach.

No, they mount in different places. The Delaney 4029XX is a 2 inch height round floor bumper, which anchors into the floor where the door edge lands. The Orca TH-3118 is a baseboard-mounted spring stop that fastens to the wall trim behind the door. If your baseboard is thin, damaged, or absent, the floor bumper is the right call; if you do not want to drill tile or finished flooring, stay with a baseboard stop such as the Orca TH-3118 or the Emtek 2231 4 inch baseboard door stop.

The Orca TH-3118 is a spring stop that cushions the door where it meets the baseboard; the opening angle is set by wherever you mount it. If you need a defined swing limit, the Hager 212 is an adjustable rigid door stop with an 80 to 120 degree range, which lets you set the stopping angle directly rather than by mounting position.

Both are baseboard-mounted door stops. The Emtek 2231 is a 4 inch baseboard door stop; the Orca TH-3118 is a 3-1/8 inch spring stop in zinc alloy. The practical difference is projection off the wall - measure from the face of your baseboard to the point the door edge or lever would otherwise strike, and pick the length that closes that gap. Sure-Loc also fills the middle of that range with the DS4 at 3-3/4 inches.

No, it only stops the swing. The 3118 is a stop, not a holder, so it absorbs the door and returns it. If you need the door to stay open, specify a door holder rather than a spring baseboard stop.
