FENCE & GATE INFORMATION

Pipe Sizes:
Elgate Fence & Gate Fittings are designed to suit standard Nominal Bore pipe sizes. These sizes are explained in the chart below. Use the chart to ensure that the pipe you intend to use is suitable, and that the fittings you require are ordered by nominal bore (internal measurement) size. This applies to all pipe connectors, such as Tees, Crosses, Corners, Multi Purpose Fittings, Stockyard Clamps and Hinges etc; as well as for Post Caps, Gate Gudgeons, Flanges, Hinges and Hinge Straps.

Thru & Butt:

Thru & Butt are the terms used to determine the pipe sizes relative to a particular pipe connector fitting. Thru describes the part of the fitting that connects with a pipe that goes 'through' the fitting. Butt describes the part of the fitting that connects with a pipe that ends at the fitting, or 'butts onto' (adjoins) the 'through' pipe. For example, a post or upright is usually the Thru pipe, and a rail connected horizontally to the post would be the Butt.

Because many fittings are designed to connect different pipe sizes, it is important to know the Thru and Butt dimensions. A Tee for example can be ordered as a T5032, which denotes 50mm Thru and 32mm Butt, or it can be a T3250, which of course denotes the opposite: 32mm for the Thru dimension and 50mm for the Butt. Below are some diagrams that may assist to understand more about Thru and Butt dimensions, but if you need more help, just: Contact Us
