Grand Slam Heavy Duty Brass Swivel Adjuster

Extra heavy duty brass adjustable swivel and hook.

Suitable for heavily used courts, e.g. clubs and schools.

Cleverly adjusts both top and bottom simultaneously by incorporating a reverse thread on the top extender. Once set, the hook is locked in place with a securing nut.

The centre guide strap is not included, although the adjuster and strap can be bought as a set together at a discounted price. Use the TE138 Grand Slam Adjuster Set link below.

Instructions for use - Adjustment is made by loosening the bottom brass locknut on the hook thread (right hand thread) and rotating the hexagonal barrel to alter the length of the adjuster. Because the top chain fitting has a counter left hand thread twisting the barrel adjusts both the top and bottom up and down simultaneously, giving an extra adjustment range not available on any other type of tennis adjuster.

Remember to retighten the bottom locknut when the correct length has been achieved.
