• The Snugulator^® is usually used on the slack side of the roller chain drive and used on the tensioned side with very little deflection.
• Snugulator^® Tighteners are available with and without flanges. Use a flanged Snugulator® for longer span chains and belts.

• The Snugulator^® should be placed a proper distance from the sprocket for minimum pressure.
• Unlike many idler sprockets, the Snugulator^® Tightener lasts a long time and is not sensitive to chain wear. Both new and worn chain can safely run on the same Snugulator^® .
