Model Description

This custom-designed Shade Cloth Clamp is engineered for securely fastening shade cloth material using a ladder-lock latch and strap system. The clamp features a durable U-shaped form, optimized for gripping fabric without tearing or slipping.

One end of the clamp includes a set of integrated gripping teeth, while the opposite end features corresponding recess holes. When the clamp is compressed, the teeth lock into the holes, holding the shade cloth firmly in place. A 5 mm bolt hole runs through both ends of the clamp, allowing a standard M4 × 15 mm bolt (with nut) to be installed, ensuring reliable tensioning and long-term stability.
For best results, use 20 mm washers on both outer sides when tightening. This distributes pressure evenly and prevents deformation during load.

The clamp measures:
• Width: 20 mm
• Length: 55 mm
• Bolt Hole: 5 mm diameter
• Recommended Bolt: M4 × 15 mm
• Recommended Washers: 20 mm OD
• Recommended Material: Stainless steel for outdoor durability

This model is ideal for:

✔ Securing shade cloths on pergolas, gardens, and patios
✔ Outdoor gear, tarps, and fabric tension systems
✔ Custom strap-and-clamp assemblies using ladder-lock latches
✔ DIY outdoor equipment where strong, compact clamping is required

Design Concept

The concept behind this shade cloth clamp is simple, strong, and weather-resistant functionality. The U-shaped body provides spring-like tension, while the tooth-and-recess system ensures a mechanical bite into the fabric. This prevents slippage, even under wind load or repeated tensioning.

The bolt-hole design allows the clamp to be locked in place after the teeth engage the cloth, making the assembly compatible with ladder-lock latch straps commonly used in outdoor gear and tie-down systems. Lightweight but robust, the geometry is optimized for printing strength while minimizing material waste.

The result is a compact, reliable, corrosion-resistant clamp suitable for long-term outdoor exposure.
