Yellow Key Clamp Mid Post Kit for 42.4mm Tube, 1100mm Two-Rail Guardrail Post, RAL 1023

The mid post kit carries a two-rail yellow key clamp guardrail between its end and corner posts, in high-visibility traffic yellow that stands out on a warehouse floor. It is everything for one 1100mm intermediate post on 42.4mm tube: an oval base flange, a 1060mm length of post tube, a four way cross at 550mm for the mid rail and a long tee on top for the top rail. The rails carry on through the post in a straight line, and the long tee lets two top rail lengths meet over the post. Tube and fittings are powder coated yellow RAL 1023 and are made mainly for indoor use. It comes loose, ready for you to assemble with a hex key. The price shown is for one complete kit; rails and floor fixings are not included.

Why use the mid post kit

Every part in one order. The base, post tube and both rail fittings come together, with the tube already cut to length, so there is nothing to measure or cut for the post.

Joins rail lengths at the post. The long tee and four way cross take a rail end from each side, so 3.5m rail lengths meet neatly over a post with no extra joints in the bay.

Seen from across the floor. Traffic yellow marks the edge of a walkway, mezzanine or machine area clearly, and matches yellow line marking and racking protection.

Level with the rest of the run. The yellow mid and corner post kits both stand 1100mm overall with the mid rail at 550mm, so both rails run level from end to end.

Where it is used

The intermediate posts of pedestrian guardrails along warehouse and factory walkways, the open edges of mezzanine floors and platforms, guarding round machinery, plant and work cells, segregation between people and forklift routes, and edge protection round loading bays and pits indoors.

Specifications

Building a yellow two-rail guardrail

Spare parts are sold singly too: the oval base flange, four way cross, long tee and 1060mm post tube.

How many do you need?

Space mid posts at up to 2 metre centres between the end and corner posts. A straight 10 metre run needs two end posts and four mid post kits. Allow two lengths of rail tube for each bay, one top and one mid.

Choosing the right size

This kit takes 42.4mm outside diameter rail, often sold as 1¼" or 32mm nominal bore, the most common size for pedestrian guardrail. For a lighter rail, use the yellow mid post kit for 33.7mm tube; for the heaviest duty runs, use the yellow mid post kit for 48.3mm tube. Keep every post, fitting and rail on one run the same tube size.

Fitting and care

Push the post tube into the oval base and tighten its grub screw. Slide the four way cross on and set its centre 550mm above the floor with the sockets facing along the run, then fit the long tee on top so the overall height is 1100mm. Stand the post in place, mark the two holes in the base, drill and fix with anchors to suit the floor (not included). Push the rail ends fully into the cross and the tee, level them and tighten every grub screw with a hex key. Check the anchors and screws after the first week and then once a year, and touch up chips with yellow RAL 1023 paint.

Outdoor note: the powder coat suits outdoor use, but the brass-coated grub screws will rust outside. If the guardrail is outdoors, coat the threads inside each fitting and the grub screws with matching yellow paint after fitting. For a long outdoor life, galvanised key clamp is the better choice.
