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.

- 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.

Chain link floor flange
I scoured the internet for one of these.most were what I call outrageously over priced.this one was in the $20 range and that includes shipping. Well, it showed up today and I am thoroughly impressed with the weight (weight = quality in my book). The picture doesn't do it justice for how Stout this thing is.

floor flange for fencing
The order and delivery process was great. Got here much quicker than even our local home stores could get a similar product. Product was heavier and of better quality that I expected.

Floor Fence Post Mount
I placed an order with your company Thanksgiving afternoon via the internet. I found out that I didn't need the merchandise so Friday morning I tried contacting your company. I could not find a telephone number so I tried e-mailing you. All of the addresses I tried, came back undeliverable. I finally called my credit company and they couldn't give me an e-mail address either. I had to wait until the merchandise was delivered and then return it per my credit card company instructions. I hope none of your customers need to contact you because your e-mail address in invalid. I tried signetfence.com; infosignetfence.com;signetfence.com/info and several other combinations and none of them worked. Thank goodness, my credit card company took care of this matter for me and they returned my money and even paid for the postage to return the merchandise. **Signet Fence Response** Hello Brenda, We appreciate your feedback. Our email is info@signetfence.com. It is published on multiple pages of our site, and elsewhere on the internet. We have used the same email address since we started selling products online in 2010, and we receive many emails at that address each day without any issues; so, our email address is definitely not invalid. Unfortunately, none of the addresses that you listed in your comment above are properly formatted email addresses, so they wouldn't work. We're sorry that you had trouble contacting us because we would have been happy to cancel your order before it shipped. Thank you, Signet Fence
