Setting out mitred corners in core rail.

One of the most common mistakes made when installing either metal or glass panels that require a timber capping, is the transition from pitch to horizontal or pitch to pitch.

This stems from the handrail flow not being calculated before the stairs are designed, or designed with the first and last riser set adjacent to the landings and therefore the transitions are not allowed for. The end result is a handrail made up from small sections that do not flow correctly and may be just glued into place as no mechanical fixing can be used.

Intersecting compound mitres rarely work when it comes to handrail; with the exception of completly round handrail and a fitter that likes danger but not his fingers!

The solution.

The way round this potential problem is to divorce the change of pitch from the change of direction by the introduction of Gooseneck transitions.

In order to achieve this you will need to know the size of the handrail profile to be used. This will allow you to calculate the size needed for the mitres in the gooseneck. This is also a good time to contact the handrailer and ask him what he needs for space in the corners.

Most handrail suppliers would rather help at this stage, rather than when it’s gone wrong.
