About this product
Eliminate Flashing and Roof Leaks With Cast Aluminum Rail Base
The Top Rack Cast Aluminum Rail Base gives installers a faster, more reliable way to secure TRT rails while protecting the roof from leaks. By bonding directly to the shingles with butyl rubber pads, it creates a watertight seal without the need for traditional flashing—delivering long-term strength and peace of mind. Whether mounted to roof decking or anchored to a rafter, the base provides a solid, code-compliant foundation built for lasting performance.
Use Cases
Used as the primary mounting base for TRT rail systems on pitched, composition-shingle roofs in residential and commercial solar installations.
- Flash-Free Roof Attachment: Bonds directly to asphalt shingles using EPDM and butyl pads, eliminating traditional flashing and reducing leak risk.
- High-Strength Cast Aluminum: Manufactured from 6005-T5 aluminum with a black anodized finish for corrosion resistance and long-term durability.
- Direct TRT Rail Connection: Designed for direct attachment to TRT rails for fast, clean rail installation.
- Flexible Rafter Alignment: Sliding base design allows up to 1″ of adjustment to align the center mounting hole with rafters.
- Certified for Safety & Fire Resistance: UL 2703 listed and maintains the Class A/B fire rating of the existing roof.
