The Slip Mount is an innovative post-mounting system that allows vinyl fence posts to be installed over galvanized round pipe without digging or using concrete. It provides a faster, cleaner, and more durable installation method compared to traditional approaches.

In the fall of 2008, a design of a post-leveling collar was developed to adapt a 5" x 5" square vinyl fence post to larger 2-3/8" pipe sizes. At that time, other post collar products were available on the market, but only for use with 1-7/8" pipe. Slip Mount became the first product to successfully adapt a square vinyl fence post to a 2-3/8" round pipe while also incorporating full adjustability. In February 2009, the product was granted patents in both the United States and Canada.

HDPE Resin (High-Density Polyethylene) High-Density Polyethylene (HDPE) is a versatile thermoplastic polymer widely valued for its high strength-to-density ratio and broad range of applications, including packaging, piping, and construction materials. Definition and Properties HDPE is produced through the polymerization of ethylene and is recognized for its durability and lightweight nature. With a typical density range of 930–970 kg/m³, it offers excellent resistance to impact, chemicals, and moisture. Its rigidity makes it suitable for demanding applications, and it can tolerate temperatures up to 120°C (248°F) for short periods. Advantages • Lightweight yet strong • Cost-effective compared to many engineering plastics • Recyclable and environmentally versatile • Resistant to UV (with stabilizers) and weathering • Excellent chemical and moisture barrier

Slip Mount is ideal for residential, commercial, and agricultural fencing projects. It’s commonly used in vinyl fencing, railing systems, pergolas, arbours even real estate signposts especially where speed of installation and long-term durability are priorities.

Slip Mount is designed to work with all standard 5" x 5" square vinyl fence posts. The system adapts these posts to round galvanized pipe (2-3/8") for a secure, adjustable fit.
