A Guide to Tarp Fasteners: DIY Clamps, Bungee Systems, and Tie-Downs

Introduction

Keeping a tarp secure is essential for shielding items from wind, rain, and sun. Whether you're covering tools, creating a temporary shelter, or protecting a vehicle, the right fastening method ensures a firm hold and extends the tarp’s lifespan.

This guide explores different ways to secure tarps, including homemade clamps, elastic cord systems, and various tie-down techniques. Each method suits specific needs, from quick setups to heavy-duty applications. By understanding the advantages and drawbacks of each approach, you can choose the most reliable option for your situation.

1. Tarp Clips

Tarp Clips provide a strong grip without relying on built-in grommets. They offer a flexible and low-cost solution, especially for those working with tarps that lack reinforced edges.

PVC Pipe Clamps

  • Cut a short piece of PVC pipe (around 1-2 inches wide).
  • Make a single cut along its length to create a flexible opening.
  • Slide the pipe section over the tarp and reinforce it with a zip tie or clamp.
  • Works well for lightweight tarps and prevents tearing.

Binder Clips and Spring Clamps

  • Large binder clips offer a solid grip and attach easily.
  • Spring clamps, found in hardware stores, provide a firm hold and last through repeated use.
  • Both options work well for securing tarps over small frames or tables.

Wooden Clamps

  • Drill a hole through two small wooden blocks.
  • Use a bolt and wingnut to adjust pressure.
  • Creates a strong, non-damaging clamp for long-term use.

Strengths and Weaknesses

Advantages:

  • Inexpensive and simple to make.
  • Work on tarps without built-in grommets.
  • Provide flexibility in securing different sizes.

Limitations:

  • Less effective in strong winds.
  • May degrade faster than store-bought options.

2. Elastic Utility Cords

Elastic Cords allow tarps to flex with wind and movement, reducing strain that could cause tears. They offer quick setup and are useful for temporary or frequently adjusted coverings.

Ball Bungees

  • Bungee Balls Feature a flexible cord with a plastic ball at one end.
  • Loop the cord through the tarp grommet and wrap it around the ball for a secure fit.
  • Well-suited for canopies, tents, and lightweight covers.

Adjustable Bungee Cords

  • Available with sliding hooks or adjustable lengths.
  • Provide a snug fit without requiring knots.
  • Ideal for irregularly shaped objects and temporary coverings.

Elastic Setups

  • Use sections of old bicycle inner tubes or rubber cords.
  • Attach hooks or loops at the ends.
  • Serve as an affordable substitute for commercial options.

Best Uses for Elastic Fasteners

  • Covers that need to be adjusted frequently.
  • Tarps stretched over rounded or soft surfaces.
  • Lightweight applications where minimal force is required.

3. Tie-Down Approaches

For more secure and long-lasting setups, tie-downs use ropes, straps, and zip ties to keep tarps firmly in place.

Knot and Rope Methods

Choosing the right knots ensures a tight hold while allowing for easy adjustments.

  • Truckers’ Hitch: Creates a secure, adjustable loop for added tension.
  • Taut-Line Hitch: Keeps ropes tight even when conditions shift.
  • Bowline Knot: Forms a stable loop that resists slipping under pressure.

Ratchet Straps for Sturdy Fastening

  • Designed for securing loads on vehicles, trailers, and heavy-duty applications.
  • Provide controlled tension through a ratcheting mechanism.
  • Highly durable and suitable for prolonged outdoor exposure.

Zip Ties for Quick Fixes

  • Fast and inexpensive way to fasten tarps to poles or fences.
  • Work well in combination with other methods for added stability.
  • Not reusable but great for temporary applications.

4. Selecting the Best Fastening System

Choosing the right fastening method depends on several key factors:

Weather Conditions

  • Windy areas require strong tie-downs, such as ratchet straps or truckers’ hitch knots.
  • Milder environments allow for bungee cords or DIY clamps.

Tension Requirements

  • Heavy-duty applications benefit from ratchet straps or knotted ropes.
  • Lighter covers work well with ball bungees or elastic cords.

Ease of Use and Adjustability

  • If frequent adjustments are needed, bungee cords are the most convenient option.
  • Fixed applications, such as truck bed covers, require more rigid fastening like ratchet straps.

Cost Considerations

  • DIY clamps and zip ties offer affordable solutions for temporary use.
  • High-quality bungee cords or ratchet straps provide long-term reliability and strength.

Conclusion

A well-secured tarp protects items from weather exposure, prevents damage, and ensures safety. Homemade clamps, elastic cord setups, and various tie-down methods each provide different levels of security and ease of use.

Experimenting with different approaches helps determine the best fastening method for your needs. By selecting the right combination of fasteners, you can keep your tarp secure in any situation, whether for short-term use or long-term protection.
