Space spindles at a maximum of 99mm apart (measured between spindle faces) to comply with current UK Building Regulations, which require gaps to be no greater than 100mm. Store spindles flat and off the ground prior to installation to avoid any distortion to the powder coat finish.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWill this spindle fit my existing handrail and base rail?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis spindle is designed for use with rails that have a 13mm routed groove.
