Size 7 Tube Three Way 90° Elbow (A18) Key Clamp Fitting

Size 7 Tube Three Way 90° Elbow (A18) Key Clamp Fitting

A Three Way 90° Elbow, also known as an A18 Tube Clamp Fitting has been specifically designed to form a 90° corner on a top tube of a guardrail or handrail application or within a table structure. This fitting unites horizontal top tubes with the vertical tube and gives the created corner a rounded finish. As well as providing an aesthetically pleasing and sleek appearance, but this rounded finish adds to the levels of safety within the structure by eliminating any harsh ends.

Two tubes will fit horizontally into the fitting, with a third tube fitting vertically into the lower part of the tube clamp; this will ultimately become an upright post within the structure. When using this type of key clamp fitting when constructing guardrail applications, use a Three Way Through Intersection (A20) fitting for tubes that appear in the middle or lower sections of the system.

Please note: The three tubes that are used in conjunction with this tube clamp fitting will need to have an outside diameter of 42.4mm, these are also known as Size 7 Tubes.

You will also need to purchase one of our Hex Keys, these help with installation by tightening the Grub Screws without the need for any expensive equipment.
