Rectangular Tube Inserts & Glides

 (3 product groups)

Rectangular tube inserts offer a clean, secure finish for open-ended rectangular tubing. Acting as protective end caps, they help prevent damage from sharp edges and enhance both safety and appearance. Designed to fit snugly into a wide range of rectangular tube sizes, these inserts are ideal for use across multiple industries.

Our range includes both push-fit and threaded designs, with options such as ribbed tube inserts for easy installation and a secure hold. These components double as tube glides, allowing furniture and equipment to move smoothly without damaging floors.

Made from high-quality materials like HDPE, LDPE, PE, and other durable plastics, each material offers specific benefits—HDPE for its rigidity and impact resistance, LDPE for flexibility, and PE for its all-around durability.

Applications include:

  • Furniture manufacturing and finishing
  • Metal fabrication
  • Mechanical structures
  • General-purpose industrial use

Whether you're protecting tubing ends or reducing floor damage, rectangular tube inserts and tube glides provide long-lasting, reliable solutions.
