Review of the 8501 Series: Norton Door Closer

Norton 8500 Series CloserToday’s article represents the first in an on-going series of door hardware reviews. I’m beginning with the Norton 8501 Door Closer partly due to its popularity, but mainly because it’s one of the items for which we have NEVER received a complaint. Not one complaint or return (or even slightly negative comment) in the 15 years we’ve stocked the closer.

EASY, RELIABLE & VERSATILE

This versatile, heavy duty door closer is easy to install and very reliable. It’s made from cast aluminum and comes with a slimline aluminum alloy shell. What I like most about it is that is is not handed. This eliminates the mistake of ordering the wrong handed closure. It can be mounted Regular arm, Top Jamb and or Parallel Arm mount. Additionally, the Norton 8501 Door Closer can be used indoors or outdoors.

It’s offered in different sizes, ranging from 2 to 6 — this is quite a help. I also like 8501 norton door closer imagethe adjustable sweep speed and latch speed, and the independent regulating set of valves.

It’s hex operated which permits latching speed and sweep speed.  Barried free option, A molded cover, Non critical valves and both adjustable delayed action and back check cushioning options. Delayed action is a must feature when it pertains to any public facility. This feature allows any handicapped or elderly person more time to enter through the door opening. It delays the action of the door closing speed. The 8501 closer can also be fitted with a hold open arm, closer plus arm, dead stop CLP-T arm and more.

If you need a heavy duty, reliable, cost effective, easy to install door closer, the 8501 Norton Door Closer is it.
