Key Clamp Open Wall Flange Pair for 48.3mm Tube, Lift-Out Rail Bracket, Galvanised

A pair of open wall flanges that carry a 48.3mm tube between two walls, so the tube can be lifted out whenever you need it. Each flange has a round plate that screws to the wall and an open U shaped cradle on the front. The tube drops into the cradles from above and one grub screw on each flange locks it, or leave the screws loose so the rail lifts straight out. They are the usual way to hang clothes rails and to fit a removable bar across an opening. They are malleable cast iron with a galvanised finish for indoor and outdoor use. The price shown is for one pair (two flanges), with a minimum order of 5 pairs.

Why use open wall flanges

The tube lifts out. The cradle is open at the top, so a rail can be taken down for cleaning, loading or access, then dropped back in. A closed wall flange cannot do this.

Fit between fixed walls. With closed flanges the tube has to be threaded in as you fix them. Here both flanges go on the wall first and the tube drops in afterwards.

Three fixings each. Three holes spread the load across the 110mm plate.

Galvanised for indoors or out. The zinc coating suits shops, utility rooms, workshops and outdoor stores.

Where it is used

Clothes and garment rails between two walls in shops, wardrobes and utility rooms, removable bars across openings and alcoves, roller and reel rails in workshops, and the ends of two part hanging systems.

Specifications

Know its limits

The cradle is open at the top, so it holds the tube from below. Fit it with the opening facing up and do not use it where the tube is pulled upwards or sideways, such as a guard rail or a handrail people lean on. For those, use a closed wall flange. No load rating is published; for a heavy load, ask a structural engineer to check the design and the wall fixings.

Which 48.3mm fitting do you need?

How many do you need?

One pair for each rail. For a long rail, add a support in the middle so the tube does not sag under load.

Choosing the right size

Key clamps are sized by the tube's outside diameter. 48.3mm is standard scaffold tube, often sold as 1½" or 40mm nominal bore. Measure across the tube before ordering: this flange will not hold 42.4mm or 60.3mm tube securely. The same pair is made for 33.7mm and 42.4mm tube.

Fitting and care

Mark the height on both walls so the rail sits level. Fix each flange with three screws or bolts up to 8mm, with plugs to suit the wall and the opening facing up. Cut the tube to fit between the flanges, drop it into the cradles and tighten the grub screws with a 5/16" hex key if the rail is to stay put. Check the screws once a year. Touch up scratched galvanising with zinc-rich paint.
