Orca Hardware 3-3/4" Spring Door Stop

The 3-3/4 inch length is measured from the mounting base to the tip, so that's roughly how far the door is held off the trim. If your door hardware projects farther than that (a wide lever rosette or a thick pull on a deep casing), you want more reach: the Delaney solid brass baseboard stop adjusts from 3-1/2 to 4-1/2 inches, and the Emtek 2231 baseboard stop is 4 inches. For a shorter run, Sure-Loc makes a 3-1/8 inch spring stop.

The Sure-Loc DS4 is a 3-3/4 inch spring door stop for residential doors, matching the Orca TH-3134 in both length and spring-stop style. Both mount to the baseboard and use a spring body with a tip bumper, so the wall strike point sits at the same height off the floor. The Orca TH-3134 is zinc alloy and comes in oil-rubbed bronze, satin nickel, polished chrome, and black, so finish match to the rest of the door hardware is usually the deciding factor.

The Sure-Loc DS3 is a 3-1/8 inch spring door stop for residential doors, about a half inch shorter in projection than the Orca TH-3134 at 3-3/4 inches. It is the same baseboard-mounted spring type, so the screw pattern and installation method carry over; you are only changing how far the stop reaches toward the door face.

For a rigid alternative, the Sure-Loc DS7 is a 4 inch solid door stop with no spring section, and the Emtek 2231 is a 4 inch baseboard door stop. Both are fixed-body stops, so the door comes to a hard stop rather than the cushioned rebound the Orca TH-3134 spring stop gives. A solid stop transfers more of the impact into the baseboard and its anchors, which is worth accounting for on hollow or thin trim.

A spring stop like the 3134 only cushions the swing, it doesn't hold the door open and it doesn't limit the opening angle to a fixed point. If you need the door stopped at a set degree of swing, use a rigid adjustable stop instead, such as the Hager 212, which covers an 80 to 120 degree range. Sure-Loc's 4 inch solid door stop is the non-spring option if you just want a fixed bumper with no flex.

Four finishes: oil-rubbed bronze, satin nickel, polished chrome, and black. That covers matching to most common lever and hinge finishes on a unit turnover, and ordering one finish across a building keeps the stops consistent with the rest of the trim.

Yes. Sure-Loc's 3-3/4 inch spring door stop is the same length and the same type, so it's a like-for-like swap if you're matching existing stops or need a second source. Sure-Loc also lists a 3-1/8 inch version if the reach needs to be shorter.

A baseboard stop like the 3134 needs solid trim or blocking behind it to take the fasteners, since all of the swing load lands on that base. Where there's no usable baseboard, go to a floor-mounted bumper instead, such as Delaney's 2 inch round solid brass floor bumper, which anchors into the floor behind the door.

The Delaney 40201X is a solid brass baseboard door stop adjustable from 3-1/2 inch to 4-1/2 inch, which brackets the fixed 3-3/4 inch length of the Orca TH-3134. For a portfolio with mixed trim depths and door swings, one adjustable SKU can cover openings that would otherwise need both a shorter and a longer fixed stop. The Orca TH-3134 is zinc alloy where the Delaney is solid brass.

No. The Delaney 4029XX is a 2 inch height round solid brass floor bumper, anchored into the floor, while the Orca TH-3134 is a baseboard-mounted stop that fastens to the wall trim. Choose by mounting surface: a floor bumper needs a solid floor you are willing to drill and works where there is no baseboard behind the door, whereas the TH-3134 leaves the floor untouched. They are not interchangeable in the same hole.

The Sure-Loc DS4 is a 3-3/4 inch spring door stop and the DS7 is a 4 inch solid door stop. The DS4 matches the Orca TH-3134 spring action and length; the DS7 is a quarter inch longer and rigid, so it stops the door without flex. Both mount to the baseboard, so the substitution comes down to whether you want a cushioned stop or a fixed one at that opening.

Orca classes the TH-3134 as commercial, and the product copy calls out residential application, so it suits multi-family and light commercial interior doors, apartment units, offices, and corridor-side bedroom doors. Zinc alloy construction is the body material. For heavier traffic or an accessible opening, look at a rigid stop instead.
