Description
This is the fitting that carries the sloping knee rail through every post on a yellow GRP stair guard rail. The post runs straight up through the cross and the knee rail passes through it at 30 degrees, the standard pitch for stairs, so both stay unbroken. It is moulded in two halves from glass reinforced plastic, so it never rusts, needs no painting and suits wet, corrosive and electrical sites. The price shown is for one fitting, with a minimum order of 5. Each cross takes three M6 rivet nuts and bolts, sold separately.
Why use a GRP 60 degree middle cross
Made for stairs. The knee rail runs parallel to a 30 degree stair while the post stays plumb, with no site bending or packing.
Both tubes stay in one piece. The post runs unbroken from base to top rail and the knee rail runs through, so there are no joints at knee height.
No rust, no hot work. GRP does not corrode, needs no painting and is assembled cold with a drill and spanner.
High visibility. Safety yellow all the way through.
Where it is used
Stair guard rails up to tanks, platforms and walkways at water and wastewater treatment works, chemical and plating plants, food factories with washdown, rail depots, cooling towers and electrical sites.

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 a mid rail at 550mm and 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 every post along the stair, where the sloping knee rail crosses it. The top of each stair post takes a 60 degree short tee.

- Tube: 5000mm lengths or 3500mm lengths

Fitting
Fix the post bases with the posts running unbroken from base to top rail. Cut each knee rail length to fit between posts with its ends cut at 60 degrees so the tube seats fully in the fitting. Close the two halves of each cross round its post and the knee rail, check the rail runs parallel to the stair, then fix each cross with its three M6 rivet nuts and bolts. Seal 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
Is the price for one fitting?
Yes, one two-part 60 degree middle cross. The minimum order is 5. The three M6 rivet nuts and bolts are sold separately.
What stair pitch does it suit?
It is moulded for a knee rail at 30 degrees to horizontal, the standard angle for stairs. For other pitches, use an adjustable joint.
Will it fit steel scaffold tube?
No. It is sized for 50mm GRP handrail tube. Steel 48.3mm tube needs key clamp fittings.
Is GRP handrail safe near electrical equipment?
GRP does not conduct electricity like steel, which is why it is chosen for rail and electrical sites. Follow your site's own electrical safety rules.
