Counter Balance Arm & Springs

Before sending us an email or placing an order, please read these Frequently Asked Questions. They contain a collection of the answers to the most common questions customers ask about ordering Counter Balance Mechanisms and Spring Kits.
Question I need to replace the hinges on my attic ladder. It was installed in 1997 and the model # is W2210, but I can't find a mark number (MK #). Can you help?
You need a "counter balance mechanism" kit # 55-1, for Werner ladders manufacturerd prior to February 2006. With this kit, you reuse your "springs" and "pivot plates" (lag bolts are also included with the kit, in case the rivet in the pivot plate has begun to pop out.)
   
Question If individual "Pivot Plates" are not available, how do I install a Counter Balance Mechanism: 55-1?
You must reuse your current pivot plates. Click here to download the installation instructions.
   
Question I have a Werner Attic Ladder and need a Counter Balance Mechanism. What part # should I order?
If your ladder was manufactured before February 2006 by Kentucky Ladder for Werner, you will need a 55-1
   
Question I have an old attic ladder and I need a Counter Balance mechanism. I have no information on the ladder and I’m not sure who the manufacturer is, but the picture of mechanism (55-1) looks identical to mine.
You would need to have a Werner ladder for this product to work. This kit will only work with the Werner ladders, and is not a "universal" product for all manufacturers.
   
Question I cannot find the Mark Number on my Werner Attic Ladder. What should I do?
If you don't find a label that includes a mark (Mk) number, the label or ink stamp indicates that the ladder was manufactured by Kentucky Ladder for Werner. Use 3 as your mark number.
   
Question I placed an order for a Spring Kit and my order has not been processed yet. Why?
Unfortunately, to process your order, we need the model and mark number (Mk) of your attic ladder.
   
Question How many springs are included on each Spring Kit?
These kits include TWO springs.
   
Question Can I order a Counter Balance Mechanism (55-1) for my Keller Attic Ladder?
The 55-1 will NOT work for your ladder.  These Counter Balance Mechanisms and Spring Kits are for Werner ladders ONLY and it will NOT WORK with any other manufactures' ladders.
