Adjustable-spigot saddles pivot freely and lock at any angle - use them on staircases where the handrail follows the stair rake (typically 30-45° pitch). On any stair install you'll need adjustable saddles - fixed saddles cannot accommodate the slope and force the handrail off the post angle.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan saddle clamps be welded to the post?\u003c\/strong\u003e\u003cbr\u003eYes - all saddle clamps in this range have a flat back face that can be MIG\/TIG welded to the post for a permanent structural fix.

For external use, marine applications, swimming pools, balconies and any salt-exposed location - always specify 316.
