Rockwood 526 4" Spring Door Stop Bright Nickel Finish

Projection is 4 inches, so the door face stops 4 inches short of the baseboard. That is what decides whether the lever or knob clears the wall: measure from the wall to the outside of your trim when the door swings open, and if the knob sticks out more than 4 inches you need a floor stop instead of a baseboard stop.

It carries ANSI A156.16 with the type designation L02061, and it is a commercial-grade item rather than a residential one. If the spec on your drawing calls out A156.16 door stops by type number, the 526 answers it directly.

The 526 is a fixed 4 inch projection spring stop, not an adjustable one. If your baseboards vary across the building and you want one part number to cover them, the Delaney solid brass baseboard stop adjusts from 3-1/2 to 4-1/2 inches. The Emtek 2231 baseboard stop is the other fixed 4 inch option if you want to match the 526's reach in a different look.

When the base is too low or the trim is wrong for a wall-mounted stop, go to the floor. The Delaney 2 inch round solid brass floor bumper mounts to the slab or subfloor and takes the door at the bottom rail. Orca also makes shorter spring stops, the TH-3118 at 3-1/8 inches and the TH-3134 at 3-3/4 inches, if you want the same spring action with less reach than the 526's 4 inches.

The Rockwood 526 is a spring base door stop with a 4 inch projection, built in steel. The nearest peers by function are the Orca Hardware 3-3/4 inch spring door stop, part TH-3134, and the Orca Hardware 3-1/8 inch spring door stop, part TH-3118. Both are spring door stops in the same flexing-post form, and both project less than the 526 at 3-3/4 inches and 3-1/8 inches respectively. If the door swing needs the full 4 inches of standoff to keep the lever or knob off the wall, the 526 is the one that carries that projection.

The Rockwood 526 is a fixed 4 inch projection spring stop, so the strike point lands in one place on every door. For a fleet where the trim is not consistent, the Delaney solid brass baseboard door stop, part 40201X, adjusts from 3-1/2 inches to 4-1/2 inches, which brackets the 526 projection on both sides from a single part number. That lets one SKU cover openings whose base trim sits at different depths instead of stocking two lengths.

They are not interchangeable, even though both stop a door. The Rockwood 526 is a baseboard-type stop that fastens to the wall base with 6 x 3/4 inch sheet metal screws and takes the door on a sprung post. The Delaney 4029XX is a 2 inch height round solid brass floor bumper, which mounts to the floor instead. Choose by where the fastening surface is: a floor bumper needs a floor you are willing to drill and a door that swings over it, while the 526 needs base trim in reach of the door edge. Carpet depth, radiant floors, and tile all push the decision one way or the other.

A spring stop like the Rockwood 526 absorbs the swing and returns the door; it does not hold it. For an opening where the door has to stay open - a corridor during a move-in, a loading area, a kitchen door - the Orca Hardware TH-30HD is a heavy duty rigid door stop whose function is a door holder. The Hager 212 is an adjustable rigid door stop with an 80 to 120 degree range, which sets where the door parks. Rigid stops transmit the impact into the wall rather than flexing, so they belong on solid backing.

It ships with 6 x 3/4 inch sheet metal screws. That length bites the baseboard and not much past it, so on a hollow or drywall-only wall you want to hit a stud or add an anchor rated for the impact. Wood base or a solid ground behind it takes the supplied fasteners as they are.

The 526 is a spring stop: the steel body flexes when the door hits it, absorbing the swing instead of transferring the whole impact into the baseboard. That is what you want on doors people push through hard. A rigid stop like the Orca TH-30HD stops the door dead and doubles as a holder, which suits a door you want parked open rather than one you want cushioned.

No handing. The 526 mounts to the baseboard where the door swings to, not to the door, so the same stop works on a left hand or right hand opening and on either leaf of a pair. Order by projection, not by hand.

That is what it is built for. It is one fixed 4 inch projection with no handing and no door prep, so a single part number covers every opening in the building where the wall is 4 inches or more from the door face at full swing. Openings where a knob or lever projects past 4 inches, or where the baseboard will not take the 6 x 3/4 inch screws, are the exceptions to plan around.

The Emtek 2231 baseboard door stop is a 4 inch baseboard stop, the same projection the Rockwood 526 carries. The difference is in construction rather than reach: the 526 is a spring stop built on steel with heavy spring construction for durable wear, while the 2231 is a baseboard door stop in Emtek's baseboard door stop series. On a high-traffic commercial corridor the sprung post is what takes repeated slamming without loading the trim; in a finish-driven interior the choice usually comes down to the look at the base.

The Rockwood 526 is a commercial-duty stop certified to ANSI A156.16 with the L02061 type designation, which is the line a spec writer or MRO buyer can put on a submittal. Among the alternatives, the Delaney 40201X baseboard stop and the Emtek 2231 baseboard door stop are the closest in form, and the Orca TH-3118 and TH-3134 are the closest in function as spring stops. If the facility standard calls the stop out by ANSI type, the 526 is the one that answers it directly.

When the base trim sits shallow or the door edge lands short of a 4 inch reach, a shorter spring stop keeps the contact square. The Orca Hardware TH-3118 is a 3-1/8 inch spring door stop and the Orca Hardware TH-3134 is a 3-3/4 inch spring door stop, both functioning as door stops in the same sprung form as the Rockwood 526 with its 4 inch projection. Measure from the base to where the door face lands at full swing and pick the length that meets it flat rather than glancing.

The Rockwood 526 is a spring stop, so the post flexes and spreads the door's momentum over the travel of the spring before the base takes any of it. Rigid stops such as the Hager 212 adjustable rigid door stop with its 80 to 120 degree range and the Orca TH-30HD heavy duty rigid stop deliver the load straight into whatever they are fastened to. On drywall over studs with no blocking behind the base, the flex of a spring stop is what keeps the fasteners in the wall; the 526 lands with 6 x 3/4 inch sheet metal screws.

Body is spring steel with a bright nickel finish. Steel is the reason it takes repeated door strikes without deforming the way a hollow brass bumper can, and Rockwood stops are the type used through institutional buildings, schools, hotels and detention work.

They are both baseboard-mounted stops but they are built from different metals. The Rockwood 526 is steel with heavy spring construction, in a bright nickel finish. The Delaney 40201X is a solid brass baseboard door stop that adjusts from 3-1/2 to 4-1/2 inches. Brass and plated steel age differently in wet or coastal environments and take finishes differently, so on a job matching existing solid brass trim the material is part of the decision, not just the dimension.
