Description
A small cast collar to dress 16mm square bar. A short cast bead, only 21mm tall and 41mm across, with a rounded cushion face and 33mm bands at the top and bottom, and a square hole through the middle. It slides over the bar to add a turned detail to railings, gates and balustrades. The price shown is for one collar, with a minimum order of 15.

Why choose this collar
Sized for 16mm bar. The 16.5mm to 18mm square hole is made for 16mm square bar, and the square seat stops it turning once it is on.
A neat detail for little cost. At 41mm across and 21mm tall, it adds shape to a plain bar without bulk.
Ready to paint. It comes in a raw cast finish and takes the same primer and paint as the rest of the ironwork.
Where it is used
Railings, garden gates, Juliet balconies, staircase balustrades and restoration work in 16mm square bar. Set them at one height to form a level band across the panel.

Fitting and care
Thread the collars onto the bars before the bars are fixed at both ends. Mark a level line across the bars, slide each collar to the line, then hold it with a small tack weld or a metal adhesive.
Wire brush and degrease, then prime with a metal primer and paint to match the rest of the ironwork. Use a zinc-rich primer outdoors.
Frequently asked questions
Is the price for one collar?
Yes, one collar, with a minimum order of 15. For a larger job, call us for a quantity price.
Will it fit 16mm round bar?
No. Its square hole is made for 16mm square bar, so round bar will either not pass through or will sit loose. Check your bar before ordering.
Can I fit it to bars that are already welded in?
No. It is a solid casting, so it has to go on before the bar is fixed at both ends.
Can it be galvanised?
We do not recommend hot-dip galvanising for this part, as cast parts can blister or crack in the zinc bath. Prime and paint it, or use a zinc-rich primer before your top coat.
Why is the hole size given as a range?
The catalogue size is 16.5mm and the dimension sheet shows 18mm. Either way it passes over 16mm square bar with a little room for paint.
