Make it step by step
- Step 01
Cut and round the strip. Mark three lengthwise holes A, B and C with adequate spacing and material around their edges.
- Step 02
Clamp before drilling holes slightly larger than the cord. Sand both mouths so they cannot cut the line.
- Step 03
Take the tarp end up through A, down through B, around the anchor and back up through C. Tie a stopper larger than C; A–B is the sliding section.
- Step 04
Slide only while slack, then let the strip tilt and grip. Repeat gentle pulls, including with damp cord. Use a manufactured adjuster if it slips.
Check before use
No cracks between holes, the stopper cannot pass through and the tilted strip holds a gentle test pull.
Limits of this project
Friction depends on wood, holes and cord. No load rating; never use for hammocks or strong winds.
Take down and restore
Release tension before adjustment, remove cord, dry and retire chipped parts.
All lashings and racks here are for light objects, never people, climbing or rescue.
