Angle Line Post (Insert Compatible) - Signature Cable - Slim Side Mount - Universal Top - Alum - 36" - 32 Degree

The Signature Cable Railing, Slim Side Mount, Universal Top Angle Passthrough Post “B-5” is the intermediate post for angled stair runs. Pre-drilled with 5/16″ offset holes on both sides to match the stair pitch, cable passes cleanly through without tension fittings. Adhesive Sleeves are required to seal each hole after cable is threaded through (36″ – 20 sleeves, 39″ – 22 sleeves, 42″ – 24 sleeves). Drilled to your stair angle, from 27° to 40°. The angle washers in the fittings come in five ranges and allow a little flex, but the post drilling does not, so confirm your stair angle before ordering.

The Slim Side Mount uses a 2″-wide, 1″-thick plate that sits behind the post and mounts to the fascia; the post then bolts through the plate into the fascia for a narrow, low-profile side-mount installation.

Available in structural aluminum, 304 Stainless Steel, or high-corrosion-resistance 2205 Stainless Steel. All posts are finished in a durable, outdoor-rated powder coat. Stainless models are also available in a brushed finish. Standard colors include Textured Black, White, and Silver. Premium powder coat options are available for larger projects or custom color needs.

The Universal Top cap fits both flat and angled handrail, providing a uniform look across level and stair sections. Available in 36″, 39″, and 42″ heights. All posts are made in America.
