Rope Knot Strength Test Fixture with Tensile Machine Adaptors

Set of grips and mandrels for tying and testing overhand and figure-eight knots in plastic rope. Used to determine knot efficiency and compare braided and twisted constructions.

Specification

Specimens are formed with a standard knot and pulled on a tensile tester using special rope fixtures. Knot efficiency is the ratio of knotted to unknotted break load. Mandrels support the rope bend radius so results are repeatable.

Features

• Fits standard tensile machines
• Steel mandrel set for bends
• Capstan sleeves with polished surfaces
• Quick pin mounting
• Suitable for 4 to 30 mm ropes
