Propalock has 7mm tolerance to accommodate fitting and minor variations in steel prop diameter that may be the result of normal wear and tear, corrosion or build-up of surface finish such as overpainting.
Propalock is fitted to the lower overtube of the steel prop.
Propalock uses a fine-pitch threaded bolt with a unique coded head.
The diameter of the lower outer tube is 60mm, the circumference is 189mm.
Propalock’s operating diameter range is 64mm when open and 57mm closed.
Propalock is designed and manufactured in England.
