Key Clamp Short Slope Tee 0 to 11 Degrees for 42.4mm Tube, Galvanised

The short slope tee joins a gently sloping rail to a vertical post, for ramps, paths and sloping ground up to 11° either way from level. The rail passes straight through the short top barrel and is held by one grub screw. The post pushes into the flared socket below and is held by a second; because the socket is flared, the post stays vertical while the rail follows the slope. It suits 42.4mm 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 short slope tee

Rails that follow gentle slopes. A standard short tee holds the rail square to the post. On a ramp or sloping path that leaves a kink at every post. This tee lets the rail run at up to 11° while the post stays plumb.

One fitting for any slope in range. The flared socket takes any angle from level to 11° either way, so there is no ordering to an exact angle.

Rail runs over the post. One continuous length of rail passes through each tee, so there are no joints at the posts.

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

Where it is used

Handrails and guard rails on access ramps, sloping footpaths and car park ramps, barriers on banks and gently sloping ground, rails at loading bays and yards with a fall, and any tube frame where a rail must follow a shallow slope.

Specifications

Know its limits

The rail must run through the top in one length; two rails cannot be joined inside this fitting. Where rails must be joined over a post, use the sloping tee piece instead. For slopes steeper than 11°, such as stairs, use the 11° to 29° short slope tee or an adjustable short tee. No load rating is published; for a guard rail that must meet a set load, ask a structural engineer to check the design.

Which 42.4mm fitting goes where on a sloping rail?

How many do you need?

One for each intermediate post on the sloping part of the rail. Posts are usually spaced up to about 2 metres apart, so a 10 metre ramp rail with six posts needs four short slope tees, plus sloping elbows on the two end posts.

Choosing the right size

Key clamps are sized by the tube's outside diameter. 42.4mm tube is often sold as 1¼" or 32mm nominal bore. Measure across the tube before ordering: this fitting will not grip 33.7mm or 48.3mm tube. The same galvanised fitting is made for 33.7mm and 48.3mm tube.

Fitting and care

Fix the posts plumb first. Put a tee on each post, lay the rail through all the barrels, and let each tee settle to the slope. Check the rail height along the run, then tighten both grub screws firmly with a 5/16" hex key. Check the screws after the first week and once a year after that. Touch up scratched galvanising with zinc-rich paint.
