Deltana DHK4 Kickdown Door Holder 4"

Kickdown holders like the DHK4 work by dropping an arm onto the floor and holding by friction, so a hard floor gives the most reliable hold. On carpet the arm can dig in and still hold, but on thick pile or a floor mat the grip gets unpredictable. If you want a rubber shoe on the arm for a non-marring, more consistent bite on finished floors, the Ives FS455 is a brass kickdown holder with a 4 inch extension and a non-marring rubber shoe.

The 4 inch is the size of the holder body itself, model DHK4. That length sets how far the arm can reach down to the floor, so it suits a normal undercut of roughly half an inch to an inch under the door. If your doors sit high off the floor, over a thick threshold or a raised transition strip, a longer body reaches further: the Orca Hardware kickdown holder is 5.275 inches.

They do two different jobs. A kickdown holder mounts on the door face and drops an arm to the floor, holding the door at whatever position you kick it down at, then releases when you lift it. A wall or floor stop only limits how far the door swings, it does not hold the door open. If the crew needs the door parked open at a spot that changes, or the door is nowhere near a wall, the kickdown is the part. If you only need to keep the lever from punching the drywall, buy a stop instead.

No. A kickdown holder physically props a fire door open and it has no fusible link or release tied to the alarm, so it defeats the self closing function a fire door assembly requires. The DHK4 belongs on non-rated doors, office and dwelling entries, patio and storefront leaves. For a rated opening that legitimately needs to stand open, you need an electromagnetic hold open tied into the fire alarm, not a kickdown.

The Deltana DHK4 is a 4 inch kickdown door holder in solid brass. If the opening sees constant use and you want a holder rated for heavier service, the Ives FS455 brass kick down door holder carries a 4 inch extension and a non-marring rubber shoe and is rated heavy duty. Both share the same 4 inch working length and the same brass material, so the footprint and the reach to the floor are comparable; the FS455 adds the rubber shoe at the contact point, which matters on finished floors in lobbies and corridors.

The Deltana DHK4 is a solid brass holder offered in brass, nickel, chrome and painted black finishes such as PVD polished brass, oil rubbed bronze, brushed nickel and polished chrome. For a satin aluminum appearance, the Ives FS455A is a 4 inch kick down door holder in satin aluminum, rated heavy duty. It matches the DHK4 at 4 inches, so the drop to the floor is the same; the difference is the finish family and the aluminum look against the DHK4's brass substrate.

The Deltana DHK4 has a 4 inch working length, which suits standard undercut over hard flooring or thin commercial carpet. Where the gap under the door is larger - thick pad and carpet, a recessed mat, or a raised threshold - the Orca Hardware 40ST Series kick down door holder measures 5.275 inches and functions as a door holder. The extra length gives you reach past the pile that a 4 inch arm cannot cover.

Solid brass, not a plated pot metal casting. Both the material and substrate on the DHK4 are brass, which is why it comes in true plated and PVD finishes rather than paint alone. Solid brass matters on a holder because the arm takes a kick every time it is set and released.

No extra hardware to order. Each DHK4 ships in an individual poly bag with its mounting hardware included, and it is sold and priced by the each, so one unit is one complete holder. What is not included is anything you would need for a hollow metal door or a hollow core slab, where the supplied wood screws will not hold and you will want machine screws or the correct anchor for that substrate.

Nine finishes on the DHK4: polished brass, PVD polished brass, antique brass, oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, and paint black. If the holder is going on a high traffic entry where hands and shoes hit it, the PVD polished brass version holds its color far better than standard lacquered polished brass, which is worth knowing when you are standardizing a fleet of doors on one look.

Deltana lists the DHK4 as commercial. That said, it is a solid brass decorative-line holder rather than a hospital or heavy traffic spec item. For a service corridor, a loading entry, or anywhere the door gets kicked open all day, the Ives FS452 and FS455 kickdown holders are both listed heavy duty, and the FS452 uses a stainless steel spring.

It mounts on the face of the door near the bottom, on the push side, and the arm swings down to the floor. Handing is not a factor: the DHK4 works on a left or right hand door and you mount it on whichever face the door swings toward. What does matter is a clear floor path under the arc of the door, and enough flat rail at the bottom of the door to take the mounting screws, which rules out a glass leaf and most narrow bottom rails.

Not exactly. Deltana's DHK4 comes in polished chrome and brushed chrome, and brushed chrome is close to satin chrome in appearance but is not the same finish designation. If you are matching an existing US26D satin chrome set across a building, the Delaney kick down door stop and holder is offered in satin chrome US26D and is the straight match.

They are the same category of part and the names get used interchangeably. The Deltana DHK4 is a kickdown door holder that stops the door from closing at a chosen position until it is manually released. The Delaney Kick Down Door Stop/Holder in satin chrome US26D is sold as a Kick Down Stop series and does the same job - the word stop in the name refers to holding the door open, not to a wall or floor bumper. If you are specifying a bumper that keeps a door from striking a wall, that is a different part entirely and neither of these is it.

The Deltana DHK4 covers chrome with polished chrome and brushed chrome finishes on a solid brass body. If the facility standard is written as satin chrome US26D, the Delaney Kick Down Door Stop/Holder is supplied in satin chrome US26D and is a Kick Down Stop series unit. For a fleet spec, ordering the same model in one finish code across every opening keeps the replacement part number consistent for whoever is doing the maintenance later.

Both Ives units are heavy duty kick down door holders. The FS452 is built with a stainless steel spring. The FS455 is brass with a 4 inch extension and a non-marring rubber shoe, which puts it at the same 4 inch reach as the Deltana DHK4 and in the same brass material. If the drawing calls out a 4 inch brass holder, the FS455 lines up with the DHK4 dimensionally; the FS452 is the choice when the spring material is what is being called out.

The Deltana DHK4 is a solid brass 4 inch kickdown holder supplied in an individual poly bag with mounting hardware. Where the contact surface is a concern - polished concrete, VCT, hardwood in a residential corridor - the Ives FS455 brass kick down door holder carries a non-marring rubber shoe at the floor end and the same 4 inch extension. Both drop to the same working length, so the substitution is dimensionally direct and the difference is what meets the floor.

Not as a like for like swap on dimension. The Deltana DHK4 is a 4 inch commercial kickdown holder; the Orca Hardware 40ST Series unit measures 5.275 inches. Both perform the door holder function, so the intent is the same, but the longer Orca arm changes the geometry at the door and the existing mounting holes will not necessarily line up. Treat it as a substitute when the undercut demands the extra length, not when you are matching an existing DHK4 on adjacent doors.
