Product Description

TC770 is used to attached handrail onto wall structure at any angle. Install the TC770 bracket onto wall using 3 x M6 concrete fasteners or 14-gauge timber screw. While the railing pipe (B34 25NB / C42 32NB / D48 40NB) could be secured using galvanised hex course self-drilling screw 12-14 x 25mm. Rivets or self-drilling screws can be supplied separately at extra cost.

Although TC770 saddles type Assist fittings are primarily designed to fit snugly on C42 diameter tubes, they may also accommodate B34 & D48 tubes with a slight central gap when fitted.

This fitting can be mounted to the wall at any angle which makes it a very versatile fitting for walled ramps and stairs. The smooth finish of the fitting complies with Australian Standards for smooth finished top handrails.
