Today, the Com-Ten pull-out tester is accepted as the world standard for direct tensile test on roofing fasteners and construction,
and the name Com-Ten is synonymous with the technique. Com-Ten has since the beginning of the 60\'s been forerunners in the development of fastener testers and mechanical attachment to suit almost all applications.

The principal objective in the use of a pull-out tester system is to validate the withdraw resistance of fixings on substrate.
During the last decade the use of pull testers has become more and more widespread. And for good reasons.
The usage of Com-Ten pull testers is a very simple, flexible and reliable method that can be used on various substrates:
Brickwork, Concrete, Masonry and with almost any situation encountered during the fixings process.

A tensile load is applied to the fixing mechanically using the hand crank of the pull-out tester.
The gauge displays and registers the peak pull-out force.
