1 Inch Square Plastic Cap

Provide a clean, finished look and essential protection for your 1-inch square tubing with our industrial-grade plastic caps. These durable caps press-fit securely to seal tube ends, preventing moisture, dirt, and pest intrusion while protecting against sharp edges.

  • Material: UV-Resistant LDPE Plastic
  • Fit: For 1" x 1" Square Tubing
  • Design: Press-Fit Ribbed for Secure Hold
  • Application: Finishing & Protection
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

Our 1 Inch Square Plastic Caps are manufactured from high-quality, low-density polyethylene (LDPE), a tough and resilient thermoplastic known for excellent impact resistance and durability. Engineered with flexible ribs on the exterior walls, these caps create a secure, friction-based hold inside the tubing, eliminating the need for adhesives or fasteners. The LDPE is also formulated for UV resistance, making it a reliable choice for long-term outdoor applications without cracking or fading prematurely. These industrial-grade caps are a staple for any fabrication or MRO project in the Los Angeles area.

These square plastic caps are a critical finishing component in a wide range of fabrication, MRO, and construction projects. They are commonly used to cap the ends of metal fence posts, furniture legs, equipment frames, and display racks. Beyond providing a professional aesthetic, they serve a protective function by covering sharp, cut tube ends, enhancing safety for personnel and preventing damage to floors and surfaces. They also effectively seal the tube interior from environmental elements, reducing the risk of internal corrosion and extending the life of your metalwork.

Specifications

  • Material: Low-Density Polyethylene (LDPE)
  • Standards: Industrial Manufacturing Standard
  • Strength/Tensile: High Impact & Abrasion Resistance
  • Dimensions: Fits 1" x 1" OD Square Tubing (for various wall thicknesses)
  • Finish: Matte Black
  • Certifications: N/A

Applications

  • Fencing & Railing: Capping posts and rails for a finished look and to prevent water ingress.
  • Furniture Manufacturing: Finishing the ends of metal table legs, chair frames, and shelving units.
  • Equipment Fabrication: Protecting frame ends on industrial machinery, carts, and workbenches.
  • Retail & Display: Providing a safe, clean finish on point-of-purchase displays and racking systems.

Target Users

Ideal for metal fabricators, fence contractors, furniture makers, and MRO teams requiring a reliable and professional finishing solution for square tubing. These caps are essential commercial hardware for projects throughout Los Angeles.

Finish Options

Our 1 Inch Square Plastic Caps come standard in a versatile matte black finish that complements most metal coatings. This finish is integrated into the material, ensuring it will not chip or peel. Please contact our Los Angeles sales team for inquiries about custom colors for bulk orders.

How to Measure

To ensure a proper fit, measure the outside diameter (OD) of your square tubing. This cap is designed for tubing that measures 1 inch by 1 inch externally. The internal ribs are designed to accommodate a range of common tube wall thicknesses for a secure fit.

Example: For a tube measuring 1" on the outside, order the "1 Inch Square Plastic Cap".
