Anti
swivel collars are needed on the Made in China or Hydro cylinder to prevent
rotational movement when a Smart reflector and sensor are installed. Rotational
movement of the cylinder causes errors with Smart. Install an anti swivel collar
on each end of the cylinder.
On the
Ab Back, Leg Curl and older Leg Press the cylinder is bolted on and the mounting
area is small. A narrow anti swivel collar makes it easier to install the anti
swivel collar and you will not need to bend the cylinder mounting brackets.
There
are two types of anti swivel collars
