Trimless Channel Letters

This Trimless Channel Letters is manufactured to order rather than picked from a catalogue: the size, finish, lighting and fixing method are all set to your site. Mounting options include freestanding, hanging, wall mount, and the fixing hardware is specified for the surface you have. Returns are formed from stainless steel, galvanized sheet, acrylic, and the face material is chosen to suit the lighting. Send the dimensions and a photo of the site and we will confirm the build on a drawing before production — MOQ is one piece and standard lead time is 7–15 working days after approval.
