Each tube is held by its own hex socket grub screw, so the fitting locks on without welding or threading. Use it where the rail needs to be a larger tube than the post. The post bore is 33.7mm and the rail bore is 42.4mm, both across the outside of the tube. The post and the rail cannot swap places, because each bore fits only its own size. The fitting is galvanised malleable cast iron. The price shown is for one fitting, with a minimum order of 10.\u003c\/p\u003e\n\u003cfigure style=\"margin:16px 0\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0621\/3002\/8778\/files\/key-clamp-short-tee-reducer-33-7mm-post-42-4mm-rail-drawing.jpg?width=1200\" alt=\"Drawing of the short tee reducer: 33.7mm bore for the post at the bottom, 42.4mm bore for the rail across the top\" width=\"1200\" height=\"1200\" loading=\"lazy\" style=\"display:block;width:100%;max-width:760px;height:auto;margin:0 auto\"\u003e\u003c\/figure\u003e\n\u003ch2\u003eWhy a reducing tee works\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eTwo tube sizes in one fitting.\u003c\/strong\u003e Without a reducer you would have to change the whole frame to one size or pack out the smaller tube inside a larger fitting.

It suits a frame where the rails are the larger section, such as a heavier top rail on lighter uprights. Because the barrel sits at 90 degrees to the socket, this is a fitting for level runs.
