This accessory pack includes a 1 metre standard surface mounted aluminium profile that measures 14×17 mm. It is designed to dissipate heat from LED strips and prolong their life, and is suitable for use with LED strips that have more than 120 LEDs per metre. The pack comes with all the necessary mounting accessories and end caps, making it easy to install and use. The linear effect of the profile enhances the overall look of the LED strip when properly installed.
