6" Kickdown Door Holder / Stop Grand Standard

No roll pin at pivot point
Mallable with a pair of pliers
Rubber shoe held on by a screw
American Made
Zinc plated steel or Brass plated

Made by Grand Specialties 606z and 606br
The 606BR is no longer manufactured 

Another feature is their well constructed shoe can be adjusted down as the rubber wears making the holder last way longer than their competitors. Another use for them is as a door floor lock if mounted on the other side of the door. Once kicked down there's no entry possible unless you slide a flat item under the door to lift the door holder leg out of the way and push the door open. It can be opened from the inside as normal with your foot or hand. A very inexpensive security lock.
