304 Stainless Steel Base Cover Plate 125mm Satin for 42.4mm Tube

A bolted base plate is a working part, and it rarely looks finished on a polished floor. This satin cover slides down a 42.4mm post and sits over a 120mm base plate, hiding the plate, bolts and weld under one clean brushed dish. It is 304 stainless steel, 125mm across, 20mm high at the edge and 22mm at the centre. The price shown is for one cover, with a minimum order of 15. The post, base plate and fixings are not included.

Why choose this cover

304 grade, for indoor and sheltered rails. 304 stainless copes well with everyday moisture and cleaning, so it suits museums, hospitals, libraries, schools, offices and shops. Salt is its weak point: near the sea, round pools, near de-icing salt or on wash-down floors, choose the 316 version of this cover.

Sized to go over a 120mm plate. With a 1.5mm wall, the inside is about 122mm across, which leaves roughly 1mm of clearance around a 120mm plate. Inside height is about 20mm near the centre, so it clears 120mm plates up to about 18mm tall, such as our 120mm slotted plate for 42.4mm tube.

A neat fit round the tube. The 42.9mm hole is 0.5mm over a 42.4mm tube, so only a hairline gap shows and the cover sits centred on the post.

For looks, not strength. The cover carries no load and is not a fixing. The base plate and anchors hold the post, with or without it.

Satin finish, ready to show. Unlike a raw cast plate, this is pressed from sheet and brushed on the outside, so it sits well beside a satin stainless tube with nothing more to do.

Where it is used

Fit it on guard rail and handrail posts along museum and shopping centre galleries, hospital and school ramps, library and office staircases and atriums, wherever 42.4mm tube stands on a 120mm plate indoors or under cover.

Specifications

Is this the right cover?

Check four things: where the rail stands, the outside of your tube, the width of your base plate and what is sticking up from it.

Fitting and care

The cover is one piece, so it must go on from the top of the post. Thread it down the tube before the top rail, cap or any bracket goes on, and tape it up out of the way while you bolt the plate down.

Plan the fixings before you drill. On a 120mm plate with an 8mm flange, M10 hex bolts with washers leave about 2mm under the cover. Stud anchors with nuts usually stand too tall. A grout bed lifts the plate and takes up the clearance too, so try the cover before the grout sets.

Lower the cover over the plate once the rail is complete. If you want it held still, use a small bead of clear silicone round the tube. Clean it with warm soapy water and a soft cloth, wiping along the brushed grain, and avoid chlorine bleach and wire wool.
