Plastic Square End Cap 80x80, Color : Black

An 80x80 mm square end cap is a plastic insert plug designed specifically to fit snugly into the end of square tubing with an 80 mm outer dimension (that’s 8 cm on each side). It 's the perfect finishing touch for larger and heavier-duty tubing used in industrial or commercial applications.

. Heavy-Duty Fit

• At 80x80 mm, it’s made for larger structures like steel frames, machine bases, fencing posts, warehouse racking, or gym equipment.

• The bigger size means better load support and more surface protection.

🔧 2. Tight, Secure Hold

• The multi-ribbed design (those layered fins) ensures a tight friction fit — even if your tube has slightly uneven walls.

🧱 3. Protects Tube Ends

• Shields the metal tubing from moisture, rust, insects, and dust.

• Prevents internal corrosion in outdoor or industrial settings.

🚫 4. Scratch & Noise Protection

• Prevents scratching floors, walls, or nearby equipment.

• Reduces metal-on-surface noise — perfect for large sliding furniture or movable frames.

🌦️ 5. Weather-Proof

• Made from durable polyethylene or polypropylene, it 's UV-resistant, won’t crack in the cold, or warp in the heat — ideal for indoor & outdoor use.

🎨 6. Neat Appearance

• Gives your work a professional, finished look.

• Covers rough or sharp tube ends for clean, flush edges.

🧰 7. Easy to Install

• Just push it in — no tools needed. For a super-tight fit, a soft mallet can help.

• Can be removed and reused if needed.

📦 Typical Use Cases for 80x80 mm Caps:

 

• Industrial shelving & racking

• Metal fabrication projects
