Specifications

Installation

Position the flange and anchor it to the surface using fasteners suited to the base material (e.g., concrete wedge anchors for slab installs, structural screws/lag bolts for wood). Cut the post to height if needed, seat it fully in the collar, and tighten both set screws until the post is secure and plumb. Re-check fasteners after initial use.

Buying Guide

• Choose the right size: Match flange size to the post outside diameter shown in the table.
• Select anchors for your surface: Concrete (mechanical wedge anchors), wood (lags/structural screws), or steel (bolts with lock washers). Follow anchor manufacturer guidance.
• Application fit: Ideal where digging is impractical (slabs, decks, rooftops, interior enclosures).
• Alignment: Use a level to plumb the post before fully tightening the set screws.

Frequently Asked Questions

Do these include anchors?

No. Set screws are included; purchase anchors appropriate for your mounting surface separately.

Are they weld-required?

No. These flanges secure the post with two set screws; welding is not required.

Can I use them on wood decks?

Yes. Use structural screws or lag bolts rated for your deck framing, and confirm local code requirements.

What post sizes do they fit?

Sizes are available for common round posts: 1-7/8″, 2-3/8″, 2-7/8″, and 4″ O.D. (see Specifications).

Will the galvanized finish hold up outdoors?

Yes. The zinc coating is designed for exterior exposure. Rinse after contact with de-icing salts to maximize service life.

Comparison
