Frequently asked questions

How much is an LCN 4050A closer?

The figure on this page comes straight from the current LCN price book, resolved live. A bare 4050A prices as a band; picking the arm and finish assembles the exact part number and settles the price.

What is the difference between the LCN 4050A and the 4040XP?

The 4050A has a cast aluminum body and cylinder with a 25-year warranty, where the 4040XP is cast iron with a 30-year warranty. Both are non-handed Grade 1 closers with adjustable spring size 1-6 and the same catalog certifications.

Is the LCN 4050A handed?

No — LCN's catalog lists the 4050A as non-handed, mounting hinge side (pull), top jamb (push) or parallel arm (push). Its hold-open extra duty arms (HEDA and HEDA62G) are the handed exceptions in the arms table.

What certifications does the 4050A carry?

LCN lists the 4050A as "Grade 1 - ANSI A156.4, UL 10C, ADA, 100 hour salt spray, meets BAA - Buy American Act", and states the closer is available with less than 5.0 lbs. opening force on a 36" door.

What arms can I order on a 4050A?

The catalog prints twelve arms for the 4050A, from the Regular Arm (REGARM) through long and hold-open variants, the Extra Duty Arm (EDA) and the Cush-n-Stop family — including the hold-open extra duty arm with 62G thick hub shoe (HEDA62G).

Does the 4050A offer a delayed action option?

Yes — the LCN catalog lists a Delay Action Cylinder (CYLDEL) for the 4050A alongside the standard Cast Aluminum Cylinder Assembly (CYL); select it as the cylinder option when ordering.
