A hybrid five knuckle hinge incorporating two styles of bearing, plain knuckle bearings at the centre, and concealed or shrouded polymer bearings at the outer knuckle load bearing faces. This allows a hinge style regularly seen in recent years to be brought into the 21st century, with polymer low friction, low maintenance bearing technology being applied to the outer bearings. This type of hinge remains a popular solution for Steel Doorsets, providing the instant reassurance of plain knuckle technology with the confident longevity of ongoing reliability of high performance polymer materials protecting against both vertical and lateral wear.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Cooke Brothers is consulted before specifying.
