Key Clamp Combination Tee Crossover for 60.3mm Tube, Heavy Frame Fitting, Galvanised, Size E

A three way joint for 60.3mm tube that holds an upright and two rails at one point. The upright and the front rail both pass straight through, and the side rail ends in a socket. Three hex socket grub screws lock it together, so it works as a tee and a crossover in one casting. It suits 60.3mm outside diameter tube, sold as 50mm nominal bore, and is galvanised malleable cast iron. The price shown is for one fitting, and you can order just one.

Why a combination tee works

Three jobs in one fitting. It replaces a separate tee and crossover at the point where a post meets two rails.

The upright stays on the outside. The upright is normally placed on the outside of the structure, which helps the frame stand square and stable.

Long lengths stay whole. The upright and the front rail run through without a cut, and only the side rail has to end at this fitting.

Where it is used

Heavy tube frames, staging and racking in 60.3mm tube, where horizontal rails meet an upright and the front rail has to carry on past the post. It is best suited to the edge posts of a frame, where the side rail runs back into the structure and the upright is on the outer face.

Specifications

Choosing the right size

Measure the outside of your tube with a caliper rather than relying on a nominal bore size on a delivery note. This fitting is for tube that measures 60.3mm across, sold as 50mm nominal bore. The bore is cast to that size, so a smaller or larger tube will not grip properly.

Fitting and care

Cut every tube square and remove any burr. Slide the upright and front rail through their barrels, push the side rail fully home into its socket and line the frame up. Tighten each grub screw with a hex key until it bites firmly, and do not overdrive it.

No load rating is published for this line. If the frame has to meet a design loading, have it assessed by a competent person before it goes into use.

Check the grub screws during routine inspections of the frame, especially where it is exposed to vibration. Galvanising needs no routine care in normal conditions, and any cut tube ends or damaged areas can be touched up with a zinc-rich paint.
