Delaney 3" Knob Protector Plate

Two different jobs. The Delaney protector plate is a 3 inch plastic shield that absorbs the knob impact at the wall, cheap to install and easy to replace in a unit turn. A wall stop actually halts the door travel: the Ives WS11 and the Ives WS33 are heavy duty stops with replaceable rubber bumpers and mount to drywall or masonry. If the door slams often or the opening is commercial traffic, put in the stop. If you just need the wall face protected on a light residential door, the plate handles it.

The Delaney plate is plastic, so it's a residential-grade part. For multi-family common areas, offices, or anywhere the door gets kicked open repeatedly, spec a heavy duty wall stop instead: the Ives WS11 or WS33 are both heavy duty and mount into drywall or masonry. Keep the plastic protector for in-unit bedroom and bath doors where the abuse is light.

Wrong part for that. A knob protector plate only shields the wall at the point of impact; it has no catch and no hold-open. For holding a door open you want a wall holder: the Ives WS20 is a manual wall holder with a hinged strike, and the Ives WS40 is an automatic wall holder with a bumper pad. The automatic version catches when the door swings to it; the manual one you engage by hand.

They solve the same problem from opposite ends of the swing. The Delaney 3 inch Knob Protector Plate is a plastic plate with a 3 inch base diameter that mounts on the wall where the knob lands, so the knob strikes the plate instead of the drywall. A wall stop such as the Ives WS33/WS33X Heavy-Duty Wall Door Stop uses a projecting rubber bumper to arrest the door before the knob ever reaches the wall. The plate protects the wall surface at the point of contact; the stop keeps the contact from happening.

A 3 inch flat protector plate has no projection to adjust, so it will not clear an obstruction. The ABH RM Series and ABH RMS Series wall door stops are offered with multiple length options, which is what lets you reach past base trim or heavy casing and still meet the door face square.

White, finish code US1. That's the only finish it comes in, so on a painted wall it reads as a white disc unless you paint over it. If a metal-finish wall bumper that matches your door hardware matters more than a flush white plate, the Emtek 2255 is a brass wall bumper with a regular rosette.

For volume work in light residential openings, a 3 inch plastic protector plate like the Delaney 457701 is the simplest approach: one part per door, mounted on the wall at the knob contact point, and replaceable without touching the door or frame. Where a door gets real abuse, step up to a wall-mounted stop such as the Sure-Loc wall bumper door stop for residential doors or the Ives WS11 for heavier traffic.

The Ives WS11/WS11X heavy duty wall stop, the Ives WS33/WS33X, and the Ives WS20 manual wall holder are all specified for drywall and masonry applications, so the same model covers a corridor with block walls and one with stud framing.

No. The Emtek 2255 is a brass wall bumper with a regular rosette, where the rosette is the trim ring around a projecting bumper that the door edge or knob hits. The Delaney 3 inch Knob Protector Plate is a flat plastic plate with a 3 inch base diameter and no bumper. The rosette on the 2255 is decorative trim for a bumper, not a protector plate.
