All Metal Construction Replacement STEEL Mechanism Bolt. This steel bolt replaces the plastic nut used in the Lazy Boy 3 position leg rest mechanism assemblies for rocker recliner chairs made by Lazy Boy since 2010. In 2010 Lazy Boy replaced the steel 3 position bolt used in their rhf (right hand facing) and lhf (left hand facing) leg rest mechanism assemblies with a plastic nut. Since the nut is made of plastic it is much more likely to fail than the original steel bolt design. The plastic nut has been used in the 3 position leg rest assembly in Lazy Boy Recliners from 2010 to present. This Lazy Boy mechanism Bolt is all steel construction and is Direct Replacement and upgrade for the OEM Plastic nut. Contact customer service for additional information and bulk pricing.
