Frequently Asked

Why is the Post Pro better than the two-piece design?

It’s stronger, easier to adjust and more accurate.

How do I know the Post Pro will work?

Over a decade, hundreds of thousands of feet of vinyl fence has been successfully installed on this and similar systems. Call it a post socket, post adapter, post collar, slip mount, post donut—all of these are inferior copies of our original product.

Does this work with any make of vinyl fencing?

Yes, as long as the external dimension of the posts is 4″ or 5″.

Where can I buy the Post Pro?

Contact us or a distributor near you.

Why haven’t I heard of this before?

This product was developed in Winnipeg, Manitoba, and has spread across Canada. Now proven in some of the harshest climates and most difficult soil conditions in the world, we are now reaching out to other markets.

Can I buy the Post Pro in sizes other than the three advertised?

Not at this time. Engineering studies have shown that a smaller pipe size will not withstand typical wind loads and any pipe size larger than 2 3/8″ reduces adjustability and increases cost.

I run a small fencing business. Can I buy in smaller quantities?

We sell in any quantity, including direct to DIY customers. Prices are based on quantity orders.

Can I buy it at my local home improvement store?

No. We offer you the best price by selling direct to you.

Unique Endeavors designed, developed and improved the Post Pro system from customer input and industry demand.
