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
- Malleable Floor Flange (this item): Tall collar with dual set screws; no welding required; versatile anchoring to concrete/wood/steel.
- Pressed-Steel Surface Flange: Often used with welded connections or bolt-through collars; product-specific designs vary.
- Embedded Posts: Highest lateral strength when set in concrete footings; requires excavation and cure time.
