Description
The ready-to-fit corner for the top rail of a yellow GRP handrail. The top corner sits on the corner post and takes the two top rails at 90°, closed on top so the corner is smooth to the hand. It arrives pre-drilled and complete with its M6 nuts and bolts, so there are no rivet nuts to set and no holes to drill on site. Moulded in two halves from glass reinforced plastic, it never rusts and needs no painting. The price shown is for one fitting with its bolts.

Why choose this top corner
Faster on site. Pre-drilled with its M6 nuts and bolts included, so fitting is a hex key job.
Smooth, closed corner. The top is closed over the post, with no open tube ends where hands slide round the corner.
Square every time. The rail sockets are moulded at a fixed 90° to each other and to the post.
No rust, no hot work. GRP does not corrode, needs no painting and goes together cold.
Where it is used
Corners of guard rails round loading dock edges, roof plant areas, chemical bunds and tanks, water treatment works, food factories, rail and electrical sites, and machine guarding.

Load tested system
The 50mm GRP tube handrail system these fittings belong to has been load tested by an independent UK laboratory as a straight two-rail balustrade, 1100mm high with posts at 1000mm centres. It carried 0.4 kN/m, above the 0.36 kN/m general duty load for industrial handrails in BS 4592-0.
How many do you need?
One on top of every 90° corner post. The same post takes a middle corner at knee rail height.
| Guard rail shape | Top corners | Middle corners |

Fitting
Cut the corner post to height so it finishes level with the run posts. Close the two halves of the top corner over the post top, push each top rail fully into its socket, check the rails are level and square, then fit and tighten the M6 bolts supplied. Seal any cut tube ends with end caps.
Care
Wash down with water and mild detergent. Check the bolts once a year and after any impact. GRP needs no painting.
Frequently asked questions
Are the bolts included?
Yes. It comes pre-drilled with its M6 nuts and bolts.
Is it steel?
No. It is moulded glass reinforced plastic, coloured yellow all the way through, so it never needs painting and never rusts.
Will it fit steel scaffold tube?
No. It is sized for 50mm GRP handrail tube. Steel 48.3mm tube needs key clamp fittings.
Can the corner be other than 90°?
No. For other angles use the adjustable joint or the 120° elbow in the same range.
