What Makes the Discovery Series Stand Out

What Makes the Discovery Series Stand Out

The key link discovery series was designed with residential projects in mind. It's a straightforward, all-aluminum system that delivers a clean, modern aesthetic at a price point that competes with traditional pressure-treated lumber railing. That's a big deal when you're trying to stay on budget without sacrificing curb appeal.

Here's what makes it a go-to option for a lot of our customers:

  • Fast installation: The discovery series aluminum railing installs up to four times faster than wood railing systems. Less time on the job means lower labor costs, whether you're a contractor or a DIYer.
  • Simplified ordering: Rail sections come boxed with top rails, bottom rails, infill, and guides included. You're not hunting down individual components or guessing what you need.
  • Clean, consistent finish: Available in a Textured Black powder-coated finish with square balusters, this system gives any deck a polished, cohesive look that works with most home exteriors.
  • Low maintenance: Aluminum doesn't rust, rot, or require seasonal sealing. Once it's up, it's up.
Built for Residential Use

Built for Residential Use

It's worth noting that the keylink discovery series aluminum railing is approved for residential use only—it's not rated for commercial applications. For most homeowners and residential contractors, that's not an issue. The system meets residential code requirements and is designed to perform in those environments for the long haul.

Specifications at a Glance

  • Material: Powder-coated aluminum
  • Available rail heights: 36" level and stair configurations
  • Rail lengths: 6' and 8' sections
  • Baluster size: 5/8" square
  • Post size: 2.5" x 2.5" surface-mounted post kits (cap and flair included)

ADA Handrail Options Available

For projects that require ADA-compliant handrails, we also carry KeyLink's ADA Straight Aluminum Handrail and the mounting hardware to go with it. It pairs well with the Discovery system and gives you a complete, code-compliant setup where needed.
