Technical Specifications

Black Plaster-In Drywall Outside Corner LED Profile For 12mm LED Strip Lights. With 14.1mm/0.56in inner width, this plaster in corner led channel can be recessed into the corner of walls or plasterboard without protruding surface, suitable for 5630 led strip lights whose PCB width does not exceed 14.1mm. Made of 6063-T5 high-quality aluminum alloy, this drywall plaster-in outside aluminum corner channel provides additional heatsinking and mechanical protection for the led light strip.

4 kinds of PC led light diffuser covers make the led lighting uniform and soft, better light diffusion effects, the difference between the black diffuser, clear diffuser, semi-clear difuser, and opal matte diffuser is the transmittance. We also provide silver, white, and black aluminum corner channels to meet your decoration style. 1m and 2m led aluminum corner profiles are available. Comes with end caps, this drywall corner led strip channel is perfect for your architectural lighting and interior lighting designs. 

 

Note:

As the 2m and 2.44m plaster-in corner aluminum extrusions are too light and long, the package size will exceed the DHL/UPS/TNT requirement (4feet), so extra long transportation costs will be required if your order is less than 10 pieces. 

If you need a full 20-meter corner channel, we recommend that you use multiple 1m/2m long channels splicing together.
