Key Clamp Middle Right Hand Sloping Side Outlet Elbow 30-45°, 42.4mm Tube, Galvanised Handrail Fitting

The corner fitting for a key clamp handrail that turns at the side of a stair and slopes down it. It sits on the corner post at knee rail height: the post runs straight through it, the level knee rail goes into one socket, and a second socket at 90 degrees in plan points down the stair so the sloping knee rail continues round the corner with no bending or welding. It suits stair pitches from 30 to 45 degrees and takes 42.4mm (32NB) tube. Galvanised malleable iron, locked with hex socket grub screws. The price shown is for one fitting, with a minimum order of 5.

Why use this fitting

Corner and slope in one. One fitting turns the rail 90 degrees and drops it down the stair, where you would otherwise need two fittings and a short link tube.

No welding, no hot work. Cut the tube square, push it in and tighten the grub screws with a hex key.

Galvanised for outdoors. Malleable iron, hot-dip galvanised to match galvanised tube.

Adjust on site. The sloping socket suits any stair pitch from 30 to 45 degrees, so it copes with real stairs that are not quite to drawing.

Where it is used

External steps at schools, offices and public buildings, stairs down from loading platforms and mezzanines, access stairs at water treatment works and plant rooms, and steps in parks and public spaces.

See all fittings in Handrails & Brackets.

Fitting

Set the corner post plumb. Slide the fitting onto the post and tighten its grub screw. Push the level rail fully into its socket, then set the sloping rail to the stair pitch and tighten all the grub screws firmly with a hex key. Check the rails are at the right height above the stair nosings and landing before the final tighten.

Care

Check the grub screws once a year on busy stairs. Treat any cut tube ends or scuffs to the galvanising with a zinc-rich paint.
