Description
The yellow oval base flange stands a 48.3mm tube post up on a concrete floor, bolted down, with no welding and no digging. The post pushes down into a closed socket, two grub screws lock it, and the oval plate is fixed to the floor through its two 14mm holes. It is malleable cast iron finished in gloss traffic yellow powder coat, RAL 1023, with brass-coated grub screws, for high-visibility safety barriers inside warehouses, factories and depots. It suits 48.3mm outside diameter tube, the same size as scaffold tube, for the heavier barriers. The price shown is for one fitting.
Why use a yellow oval base flange
Posts without concreting in. Bolting each post to the floor means no core drilling, no holes to dig and no waiting for concrete to cure, so a barrier can go up in a working warehouse and be in use the same day.
Seen from across the floor. Yellow feet and posts mark the barrier line clearly for pedestrians and forklift drivers, so the base is not a trip hazard nobody notices.
Strong in the direction that matters. The plate is longest across its two bolt holes. Fitted with that long side at 90° to the line of the rail, it resists people leaning on, or trolleys knocking into, the barrier.
Easy to move. Undo two anchors and the post lifts away when the floor layout changes.
Where it is used
Pedestrian walkway barriers in warehouses and distribution centres, guards round machinery, racking end protection rails, loading bay edge rails under cover, battery charging area barriers and mezzanine edge rails.

Choosing the right size
Key clamps are sized by the tube's outside diameter. 48.3mm tube is the same size as scaffold tube, often sold as 1½" or 40mm nominal bore. Measure across the tube: this flange will not grip 42.4mm or 50mm tube. For 42.4mm tube use the yellow 42.4mm oval base flange.
Indoors or outdoors?
Powder coat looks best and lasts longest indoors. The brass-coated grub screws will rust outside. If you do fit the flange outdoors, coat the threaded holes and grub screws with matching RAL 1023 yellow paint once tightened. For outdoor barriers that need no upkeep, choose galvanised fittings.
Fitting and care
Mark each plate with its long side at 90° to the rail line. Drill the floor for M12 anchors, clear the dust and fix the plate down. Push the post fully into the socket, plumb it and tighten both grub screws with a 5/16" hex key. Touch up chips with RAL 1023 paint. Check the anchors and screws after the first week and once a year.
Frequently asked questions
Is the price for one fitting?
Yes. The price is for one oval base flange with both grub screws. Floor anchors are not included. For a full barrier, call us for a price.
Which way round should the plate go?
Put the long side of the plate, through both holes, at 90° to the line of the rails for the most resistance to people leaning on the barrier.
Can I use it on a slope?
Only on a level floor. The socket is fixed upright.
Is a load rating published?
No load rating is published for this fitting. For a barrier that must meet a set load, ask a structural engineer to check the post spacing, anchors and floor.
