This fitting joins two tubes into a tee joint. It is mainly used in handrails where the top rail is required to meet Australian Disability Standard: AS1428. It is only available in size C and D.
This fitting requires the handrail tube to be drilled and fastened with appropriate screws or rivets (not supplied).
The fitting can then be attached to stanchion post in C42 (TC755C) or D48 (TC755D). The assembly comes from TC555, TC173F, bolt and nut
Often used with TC754 for change direction, BAR 723 for J Bend Handrail Termination or TC765 for Wall End Railing Termination or TC767 for End Post Termination
