1-1/4 Inch Square Plastic Cap

Provide a clean, professional finish and essential protection for 1-1/4" square tubing with our industrial-grade plastic caps. Designed for a secure press-fit, these caps prevent water and debris from entering the tube, protecting against internal corrosion and providing a safe, non-sharp edge. They are an essential hardware component for MRO and new fabrication projects.

  • Fits 1-1/4" OD Square Tubing
  • Durable Weather-Resistant Plastic
  • Secure Press-Fit Design
  • Application: Fencing, Furniture, Equipment
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

Manufactured from high-quality, durable Low-Density Polyethylene (LDPE), our 1-1/4" square plastic caps are engineered for longevity in industrial and commercial environments. This material provides excellent impact resistance and flexibility for a secure, lasting fit. The composition includes UV inhibitors to resist degradation from sun exposure, making them suitable for both interior and exterior applications. The press-fit design, featuring flexible ribs, ensures easy installation without adhesives while creating a tight seal on the end of the tubing to keep out moisture and dirt.

These square caps are a critical finishing component in a wide range of fabrication and MRO tasks. They are commonly used to cap the ends of fence posts, gate frames, metal furniture legs, and equipment frames. By sealing the tube, they prevent injury from sharp metal edges and stop the accumulation of moisture, which can lead to rust from the inside out. They provide a professional aesthetic for ornamental ironwork, handrails, and other architectural metal projects, making them a staple for any Los Angeles industrial supply inventory.

Specifications

  • Material: Durable LDPE (Low-Density Polyethylene) / Industrial-Grade Polymer
  • Standards: Meets general industrial quality standards
  • Strength/Tensile: High Impact & Weather Resistance
  • Dimensions: Fits 1-1/4" OD Square Tubing (1.25" x 1.25")
  • Finish: Black Matte / Textured
  • Certifications: N/A

Applications

  • Fencing & Railing: Capping posts and rails to prevent water ingress and provide a finished, safe look.
  • Metal Furniture: Finishing the ends of table legs, chair frames, and commercial shelving units.
  • Equipment & Machinery: Protecting frame ends on industrial carts, racks, and machinery from damage and debris.
  • MRO & Safety: Replacing worn or missing caps and covering sharp, exposed tube ends for safety compliance.

Target Users

Ideal for metal fabricators, fence contractors, furniture manufacturers, and maintenance professionals in the Los Angeles area requiring a reliable and aesthetic finishing solution for commercial-grade square tubing.

Finish Options

Our 1-1/4" square plastic caps are stocked in a standard, non-reflective black matte finish. This versatile finish complements most paint and powder-coating colors used on metal tubing, ensuring a seamless and professional appearance for any project.

How to Measure

To ensure a proper fit, measure the outer diameter (OD) of your square tubing across the flat sides. This cap is designed to fit a tube with an exterior dimension of exactly 1-1/4 inches by 1-1/4 inches. The cap's internal ribs will adjust for minor variations in tube wall thickness to provide a secure fit.

Example: For a 1-1/4" OD square tube, order the 1-1/4" Square Plastic Cap.

  • Product name and required dimensions (1-1/4" Square Plastic Cap)
  • Confirm tubing Outer Diameter (OD)
  • Specify required quantity (available individually or in bulk)
  • No finish requirements needed (standard black)
