173 - Acute Angle Tee
| Material/Finish: Aluminum Satin Anodized |
| Pipe Size: 1-1/2" IPS |
Product Description
The Hollaender Interna-Rail® 173 – Acute Angle Tee is a precision tee fitting designed for ADA-compliant handrail systems used on stair installations. This fitting is specifically intended for use on the right side of a stairway going down, allowing the horizontal handrail to transition cleanly while maintaining a continuous, code-compliant gripping surface.
Interna-Rail® is a fully mechanical modular handrail system that delivers the sleek appearance of welded rail without the need for on-site welding. The 173 Acute Angle Tee connects to internally riveted tubing using tubular rivets and socket head cap screws and requires a Rivet Nut Tool for proper installation. Its anodized aluminum construction provides excellent corrosion resistance, while integrated set screws create a rigid, maintenance-free joint suitable for public and commercial environments.
