Quality, Strength & Elegance

Clean lines, a minimal profile, and high-quality construction make Signature series railing the perfect choice anywhere safety and preserving your view are the top priorities. Side mount posts include a removable bracket for securing railing to the fascia or outside of a structure. This can be especially advantageous where surface space is limited, or stairs are involved. Each tensioning post has been drilled and tapped to accept Cable Bullet kits (sold separately). Cable rail fittings easily attach to the inside of each post, so wires can be tensioned out of sight without the need for bulky, external turnbuckles. Every post also includes a modern stainless steel post top for mounting any handrail with a flat underside.

Complete your modern railing with ultra-slim side mount line posts and cable spacer bars and enjoy an unobstructed view from your deck, balcony, or stairway.

Please Note: Side-mount brackets are optimized for use on wood structures only and should not be attached to concrete or stone! Mounting screw holes are tightly spaced to maximize their holding strength in wood. However, in a masonry application, this highly increases the likelihood of damage between adjacent pilot holes, compromising the safety of your railing. Signature series top mount posts are designed for use in most masonry applications.

Sleek Profile, Less Hardware

A slim 2 x 2-inch column profile designed around Cable Bullet concealed tensioners. No more bulky turnbuckles or extra hardware!

Heavy-Duty, Thick Walls

Designed to withstand cable rail tension, Signature series post walls are industry-leading, 1/4-inch thick throughout.

High-Quality Construction

Post bodies are made from type 6061 structural aluminum and heat-treated with a T6 temper 6061 to provide maximum hardening and yield strength.

Machined Stainless Steel Top

Each handrail mounting bracket is machined from solid, type 304 marine-grade stainless steel. Mount any handrail with a flat underside.

Architectural Grade Powder Coating

Updated for 2022, the new fine textured powder coat provides extra durability with high performance for outdoor projects. Enjoy clean railing without chipping or scratches!

Installer-Friendly Design

Simplify the post installation process and have more flexible placement options on stairs by setting and leveling your bracket first. Once the bracket is plumb, simply attach the post column to the bracket!

Make the Most of Your Space

Mount your railing to the outside face of your deck or stairs and avoid losing valuable real estate compared to surface mount railing.

Ready for Cable Bullet Tensioners

Corner, 2-way, and end posts are all pre-drilled and tapped to accept Cable Bullet concealed tensioner kits!

What tools & supplies will I need to install my posts?
