Identify your Norton closer series

Most Norton parts are listed for one or more closer series, so read the series on the closer body or cover first. The parts in our catalog fit the 1600, 7500, 8000 and 9300BC Series, the 78-B/F Series traditional closers and the 410 Series, and many arms fit several of them at once, for example arms listed for 1600, 7500, 8000 and 9300BC. If your closer is an older model, such as a 149A, send us the model and photos and we will check what fits.

Norton door closer arms

The arm is the most replaced part of a closer. Choose it by mounting and function: regular arms (7701-1, 7701-3) mount on the pull side, top jamb arms (7701-1A, 7701-1B and the 7701-3A, 7701-3B hold open versions) mount on the frame on the push side, and parallel arms (7701-8, PR7701-5) mount on the push side of the door. The J and JL suffixes are two top jamb arm versions; check the listing and the closer's template to confirm.

Unitrol arms: closer and stop in one

A Unitrol arm combines the closer arm with an overhead stop, and Norton sizes it by door width. The catalog lists non-hold open Unitrol arms for 28" to 32" (6100-11), 33" to 41" (6100-13) and 42" to 48" (6100-14) doors, hold open versions for 33" to 41" (6100-3) and 42" to 48" (6100-4), and top jamb Unitrol arms for frame depths of 2-1/8" to 3-1/4" (J6100-4, J6100-7) and 3-3/8" to 4-1/4" (J6400-4). The 6190 and 6191 are Unitrol soffit support and wide frame reinforcing kits.

Drop plates, soffit plates and transom brackets

These plates solve mounting problems. Drop plates lower the closer where the top rail is narrow or the ceiling is low, such as the 1687 low ceiling and 1688 narrow top jamb drop plates for the 1600 Series and the 8146, 8148 and 8158 for the 8000 Series. Soffit plates (1618, 1618A, 1628H, 2018S) mount the arm under a deep frame soffit. The 2019L and 2022 angle brackets mount the closer on a flush rabbeted or flush transom.

Replacing a Norton closer body

If the closer leaks oil or will not control the door, replace the body and keep a good arm. The Norton 1601LAP is listed as a multi-sized body only for the 1601 Series. Match the series and the arm before reusing it. Covers such as the 1600P and 8400P finish the new body.

Frequently Asked Questions

Who makes Norton closers?

Norton door closers are made under the Norton Rixson brand of ASSA ABLOY. The parts in this category are for Norton surface closers such as the 1600, 7500, 8000, 9300BC and 78-B/F Series, and each listing names the series it fits.

What are the parts of a door closer called?

A surface closer has a body (the cylinder with oil and spring), an arm that links it to the door or frame, a cover, and mounting parts such as drop plates, soffit plates, brackets and sex nuts. Norton lists each one separately for its closer series.

What are some common problems with door closers?

Common problems are oil leaks from the body, a door that slams or closes too slowly, a bent or broken arm, and a closer that has pulled loose from a weak frame or door. Leaks usually mean replacing the body, while slamming or slow closing is often fixed by adjusting the valves.

Do you have parts for an old Norton 149A closer?

The parts in this category are listed for the 1600, 7500, 8000, 9300BC, 78-B/F and 410 Series. For older models such as the 149A, send us the model and photos of the closer and arm, and we will check whether a part or a replacement closer is the better option.
