Hollaender 42-8 Round Base Flange

Round Base Flange For 1-1/2 in Pipe

The Hollaender 42-8 is an aluminum round base flange designed to secure 1-1/2 inch structural pipe with an actual outer diameter of 2 inches. It provides a fixed mounting point for handrails, guardrails or structural frameworks in commercial and industrial settings. The corrosion-resistant gray mill finish suits outdoor and exposed installations.

Suited For Permanent Pipe Mounting

This flange suits installers who need a permanent, bolt-down base for 1-1/2 inch pipe structures such as railings or awning frames. It is not for applications requiring a swivel, adjustable angle or slip-on connection without fastening hardware. Builders needing a side-outlet tee, cross fitting or wall-mounted bracket should look at other fitting types.

ASTM B179 535 Aluminum Alloy Construction

The fitting is manufactured to ASTM B179 535 specification, confirming the aluminum alloy grade and mechanical properties for structural use. This standard is the primary indicator of whether the material meets the project engineering requirements for strength and corrosion resistance. Verify the specification against your design documents before ordering.
