A coordinated system, not a parts guess.

Confirm each component against your layout. The final quote should identify what is included and what must be ordered separately.

Panels & infill
Choose the layout first. Confirm panel dimensions, picket spacing and whether the section is intended for level or stair use.
Posts & bases
Confirm post locations, finished railing height and mounting method against the structure below the deck surface.
Rails & connections
Check straight, corner and stair connections. Do not assume existing cable railing components are interchangeable.
Mounting hardware
Confirm fasteners, anchors, caps and covers for the selected system and mounting surface. Check the final parts list for exclusions.

Before you choose

Is this the same as aluminum cable railing?

No. This category uses vertical pickets between the rails. Cable railing uses horizontal steel cables. The components and installation requirements may differ.

What is included in a railing kit?

The included parts depend on the confirmed product or quotation. Check the itemized list for panels, posts, connections, mounting hardware and finishing pieces before ordering.

What should I send for a project quote?

Send the length of each run, corners and openings, stair dimensions if applicable, mounting surface, project location and photos or a sketch. Note any requirements from your installer or local building department.

How do delivery and returns work?

For in-stock railing parts, estimated delivery is 5-7 days after ordering, with returns or exchanges within 30 days of delivery subject to the return policy. Availability and delivery for your selected aluminum railing configuration must be confirmed before purchase.
