The BT7841 Ø50mm Accessory Collar is a core component of the ‘System 2’ range and is designed to attach a variety of different mounts and accessories onto B-Tech poles. The 2-piece split design makes installation quick and simple and also allows accessories to be retro-fitted to existing installations without the need to disassemble anything. Finished installations look neat and tidy thanks to plastic cover plates which are included as standard.
