The LC Video Screen series brochure and user manual up to and including Revision E contain an incorrect part number for the half conical coupler needed to surface-mount LC panels.
The incorrect part number is 26820300. This half conical coupler can be fastened to a surface but does not have a hole for a spigot. It can therefore only be used in situations where LC panels do not need to be secured to the coupler (we use it inside LC flight cases, for example).
The correct part number is 21021152. This half conical coupler can be fastened to a surface with an M12 bolt and has a hole for a spigot so that an LC panel can be secured to the coupler. This coupler is suitable for installations where panels must be fastened to a surface or secured on a floor.
We have just corrected this part number and clarified conical coupler details in the LC Series specifications under Support on www.martin.com
