304 Stainless Steel Base Cover Plate 105mm Satin for 48.3mm Tube

Base plates and anchor bolts do their job, but they spoil the look of a finished lobby or stair. This satin cover slides down a 48.3mm post and sits over a 100mm base plate, hiding the plate, bolts and weld under one clean brushed dish. It is 304 stainless steel, 105mm across, 18mm deep at the edge and 20mm 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

Sized to go over a 100mm plate. With a 1.5mm wall, the inside is about 102mm across, which leaves roughly 1mm of clearance around a 100mm plate. The inside height is about 18mm at the edge, so check it against your plate and bolts before you commit.

A neat fit round the tube. The 48.9mm hole is 0.6mm over a 48.3mm 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.

304 grade for indoor work. It suits dry internal spaces and sheltered spots. Near the sea, around road salt or on floors that are washed down often, choose the 316 cover.

Where it is used

Fit it on handrail and guard rail posts in hotel lobbies, shopping centres, libraries, schools, offices and shops, on stairs, landings and galleries, and anywhere else that bolts on show would look out of place.

Specifications

Is this the right cover?

Check three things: 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.

Clearance is tight, so plan the fixings before you drill. Stud anchors with nuts usually stand too tall for the 18mm inside height; low profile hex bolts with washers are the better choice. 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. Wipe it clean with a damp cloth along the brushed grain.
