This fitting is designed for palm fixing guardrailing and balustrading to walls, parapets, steps, and ramps. The upright cannot drop through the socket. Access to the top fixing hole is restricted by the position of the flange to the barrel. When selecting a hexagon head bolt or similar bolt fixing, the maximum length of the bolt including the head must not exceed 1". Should an upright be required to pass through the fitting, the base can be bored out to order. Ø indicates diameter of fixing holes.
