Zeppelin Bend
Also known as:Rosendahl Bend
Description
A secure, symmetrical bend known for being easy to untie even after heavy loading. Two interlocking loops form a compact knot that resists jamming.
Common Uses
Joining two ropes of equal or similar diameter where easy untying after loading is important.
When to Choose This Knot
Choose this knot when joining two rope ends. Bends work best when rope diameter, material, surface texture, and expected load are considered together.
Safety Notes
- Avoid joining ropes of very different diameter or stiffness unless the bend is designed for that purpose.
- Set both sides evenly and leave enough tail on each rope.
- Do not use an unfamiliar bend in a life-safety system without supervised practice and inspection.
How to Tie
- 1Form a loop in each rope end, with the working ends on opposite sides.
- 2Cross the two loops so one working end goes over the other.
- 3Pass each working end through the other's loop from underneath.
- 4Pull all four ends to tighten. The knot should sit flat and compact.
Common Mistakes
- Tying the two sides asymmetrically.
- Using a bend for a slippery cord without adding the required backup or stopper.
- Assuming a bend that works in dry rope will behave the same when wet, icy, or dirty.
