Square Tube Inserts - Multi Purpose

In stock

Multi-function Square Tube Inserts are an ideal choice when aesthetics of your final product is not a priority. They fit tightly into square tubing, posts or poles and prevent contamination, while offering safety, and a clean finish from sharp edges on freshly cut tubes.

A practical and cost-effective range that includes thinner walls and a wide variety of sizes, fulfilling the essential requirement of tube insert protection. They are a practical choice, particularly if the appearance of your application is not a crucial factor.

Easy to install by hand-pressing or with the use of a mallet, resulting in a quick and efficient assembly process. They can be used in machine building or any application where structural tubing is required. It is advised to choose a coloured option to improve the asthetical appearance of your finished project, as it will blend with the paint and provide a pleasing visual finish.

  • Fits tightly into square tubing, posts or poles.
  • Easy to install by hand-pressing or with a mallet.
  • Used in machine building or where structural tubing is required.
