Description
A black hook clip that clamps onto 33.7mm tube and gives you an open hook to hang the end of a chain on, so the chain lifts off whenever you need to get through. The ring slides over the tube and locks with one hex socket grub screw at any height. A curled hook is cast on the side of the ring, opening upwards and parallel to the tube, so a chain link drops on and lifts off in one movement. Use it on posts either side of a doorway, stair top, bar counter or staff area to close the gap with a chain. The black electrophoretic finish matches black key clamp tube for indoor work. The price shown is for one hook clip, with a minimum order of 15.
Why fitters use it
A chain that opens in a second. Lift the end link off the hook to open the gap, drop it back to close it. No clips or shackles to undo.
Fits on the post you already have. The ring clamps round the tube, so there is no drilling or welding, and the height can be changed later.
Black to match black frames. It suits black tube posts and guardrails in bars, cafés, shops and offices.
Small and tidy. The hook sits close to the post, so it does not snag people walking past.
Where it is used
Chains across staff-only areas, bar and counter gaps, cloakroom and storeroom doorways, queue lines, the tops of ladders and stairs to mezzanines, and access gaps in indoor guardrails.

Choosing the right size
Key clamps are sized by the tube's outside diameter. 33.7mm tube is often sold as 1" or 25mm nominal bore. Measure across the tube before ordering: this fitting will not grip 26.9mm or 42.4mm tube. The same black fitting is made for 26.9mm tube. For outdoor use, choose the galvanised 33.7mm version.
Fitting and care
Slide the clip onto the post, set the height and turn the hook to face the gap, then tighten the grub screw with a hex key. Fit a matching clip or a fixed eye on the post opposite and hang the chain between them. Wipe clean with a damp cloth and touch up chips with black paint. The electrophoretic coat is for indoor use only.
Frequently asked questions

Yes. The price is for one hook clip, with a minimum order of 15.
Is the chain included?
No. The clip only. Use a chain with links that drop easily over the hook.
