Key Clamp Long Slope Tee 11-29 Degrees, 48.3mm Tube, Galvanised

The long slope tee joins a sloping rail to a vertical post on a ramp, stair or steep bank where the rail runs at 11° to 29°, and lets two lengths of rail meet inside it over the post. The rail runs through the long barrel, held by a grub screw near each end, so a joint between two rail lengths can sit inside the fitting. The post pushes into the angled socket below and is locked by a third screw, so the post stays plumb while the rail follows the slope. It suits 48.3mm outside diameter tube and is malleable cast iron with a galvanised finish for indoor and outdoor use. The price shown is for one fitting, with a minimum order of 5.

Why use a long slope tee

Join rails where they meet a post. Tube comes in set lengths, so on a long sloping run the rail has to be joined somewhere. The long barrel lets two lengths butt together inside the fitting, each held by its own screw, so the joint is hidden and carried by the post.

For steeper slopes. The socket is shaped for rails at 11° to 29°, which covers steep ramps, banks and many stairs. For gentler slopes use the 0° to 11° version.

Works with the other slope fittings. Used with the short slope tee and the 4 way slope cross, it builds two and three rail guard rails on sloping ground.

Galvanised for outdoors. The zinc coating protects the iron on ramps, stairs and banks in all weathers.

Where it is used

Top rails of handrails and guard rails on steep access ramps, external steps and stairs, guard rails on banks and embankments, sloping walkways and gantries, and any tube frame where a rail must run at 11° to 29° and be joined over a post.

Specifications

Know its limits

The fitting suits rails between 11° and 29° only; outside that range use the 0° to 11° fittings or adjustable fittings. The post ends in the socket below and cannot pass through. No load rating is published; for a stair or ramp guard rail that must meet a set load, ask a structural engineer to check the design.

Which 48.3mm slope fitting?

How many do you need?

One on the top rail at each post where two rail lengths meet. On posts where the rail runs over without a joint, the short slope tee is enough.

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: this fitting will not grip 42.4mm or 60.3mm tube. The same long slope tee is made for 42.4mm tube.

Fitting and care

Set the posts plumb and cut them to height. Push the fitting onto the post, feed the rail lengths into the barrel from each end so they meet in the middle, set the rail to the slope and tighten all three grub screws firmly with a 5/16" hex key. Check the screws after the first week and once a year, and touch up scratched galvanising with zinc-rich paint.
