Description
A 316 stainless flat post cap with an M8 threaded centre, for the top of a 48.3 x 2.0mm post. The knurled plug hammers into the post and the flat 48.3mm head sits flush with the tube, closing the post top neatly. The threaded hole in the centre takes an M8 handrail support pin or bracket, so the capped post becomes a handrail support with no welding. The price shown is for one cap, minimum order 5.

What you get
| Sold as | One flat post cap, minimum order 5 |
|---|---|
| Cap | Flat head, knurled hammer-fit plug and M8 threaded centre, 316 stainless, satin |
| Not included | The handrail pin or bracket, the post and the rail |
Why choose this post cap
Caps the post and carries the rail. One part closes the open post top and gives a strong threaded fixing for the handrail support above it, so a run of posts and rail goes together on site without welding.
Hammer fit. The knurled plug is sized for the bore of 48.3 x 2.0mm tube, the standard handrail tube, and grips as it is tapped home. Bond it in for a permanent fix.
Flush, flat finish. The 48.3mm head is the same size as the post, so the top looks clean with just a fine joint line.

Fitting
Cut the post square to height and deburr the inside. Line up the cap and tap it home with a soft mallet until the head meets the tube all round. For a permanent fix, put a little retaining adhesive or structural adhesive made for stainless steel on the plug first. Screw the M8 handrail pin or bracket into the centre thread, then fit the rail.
Care
Outdoors, rinse the posts and fittings with fresh water and wipe along the grain every few weeks, more often near the sea or a pool. Use warm soapy water; avoid chlorine bleach, wire wool and scouring pads.
Frequently asked questions
Is the price for one cap?
Yes, one flat post cap. The minimum order is 5, one per post.
Will it fit 48.3 x 2.6mm tube?
No, the plug is too big for the smaller bore of 2.6mm wall tube. Use the flat M8 cap for 48.3 x 2.6mm tube.
Can I use it as a plain end cap?
Yes. Without a pin it is a neat flat cap; the small centre hole can take a stainless M8 grub screw to close it.
