Digger Specialties Inc. (DSI), a leading manufacturer of outdoor living products, has added a stunning new color option to the TRX B-Series vinyl railing system.

The exclusive look of Black Onyx top rails accompanied by ¾" round black aluminum infills is contrasted with white vinyl posts, caps and bottom rails. The elegant tuxedo inspired color combination provides upscale curb appeal to residential and commercial properties. This eye-catching design enhancement is achieved by applying a sleek black onyx wrap to the white top rail of TRX B-Series railing.

 The TRX B-Series railing system incorporates proprietary laminated black top rail surfaces that are highly resistant to fading. Durable black aluminum infills are available in a choice of satin black or black fine texture finishes. TRX B-Series railing comes in 4', 5', 6', 7', 8', 9', and 10' pre-assembled regular and stair sections in 36" or 42" heights.  TRX B-Series railing is available with matching TRX gates in a variety of widths. DSI stands behind all vinyl railing models with a transferrable lifetime limited warranty.

“We are excited to introduce the Black Onyx Top Rail to our TRX vinyl railing product group” said Lawrence Boyts, VP of sales and marketing at DSI. “This product addition provides a stylish option for homeowners and commercial property owners by elevating their outdoor spaces with elegance and refinement.”
