Spindle Fitting Guide 

Our spindles are supplied in two sizes. The 900mm spindles are used on both closed string staircases and landings. The 1100mm spindles are used on cut string staircases so that you have one 900mm spindles and one 1100mm spindle per tread. Spindles should be fitted to the handrails & base rails by gluing and cross pining them before installing the fillets/ spindle spacers between each of the spindles. N.B. All our handrails and base rails are supplied with spindle spacers.

Current building regulations state that a sphere of 100mm diameter should not be able to pass anywhere between two spindles. Spindles should not be spaced more than 99mm apart between the narrowest parts of the spindle.

To calculate the number of spindles required use the following.

Landing Spindles – Measure the length of your rail between posts in mm’s and divide this number by 121 and round up to give the number of spindles you require

Stair Spindles – As a rule two spindles per tread and deduct a spindle for every newel post
