Made of 6063-T5 high-quality aluminum alloy, this inside corner drywall led strip light channel provides additional heatsinking and mechanical protection for the led light strip.

Opal PC led light diffuser cover makes the led lighting uniform and soft, better light diffusion effects. We also provide silver and black aluminum corner channels to meet your decoration style. 1m and 2m led aluminum profiles are available. Comes with end caps, this drywall aluminum corner channel is perfect for your architectural lighting and interior lighting designs. 

 

Note:

As the 2m extruded aluminum corner profiles are too light and long, the package size will exceed the DHL/UPS/TNT requirement (4feet), so extra long transportation costs will be required id your order is less than 10 pieces. 

If you need a full 20-meter plaster-in corner led profile, we recommend that you use 20pcs 1-meter or 2-meter long channel splicing together.
