Adjustable Elbow for 1-1/4 in Pipe

The Hollaender 3AE-7 is a corrosion-resistant aluminum fitting designed to connect 1-1/4 inch pipe in structural assemblies. Its adjustable design allows installers to create angled joints without fixed-angle constraints, suiting modular frames, railings and shelving builds.

1-3/4 in Inner Diameter and 1-5/8 in Outer Diameter

The fitting accepts pipe with a 1-5/8 inch actual outer diameter and provides a 1-3/4 inch inside diameter for flow or wire passage. Overall length measures 7-5/8 inches, giving adequate engagement while keeping the joint compact. The mill-finish aluminum meets ASTM B179 535 for corrosion resistance in outdoor or damp environments.

Connection Fitting for Modular Structures

The elbow integrates directly with 1-1/4 inch nominal pipe, requiring no welding or threading to assemble a rigid corner. Its adjustable nature frees the builder from pre-planning exact angles, while the corrosion-resistant alloy reduces long-term maintenance on exposed installations.
