Some LENTON LOCK Bolted Couplers may not be available in all regions.
Bolt length may vary after the bolt heads are sheared off. Bolt heads are not required to be removed as long as the appropriate bolt torque is achieved.
When using an air impact wrench, check the air pressure, torque rating and air flow requirements before starting installations. It is recommended to use an impact wrench rated 2X the bolt torque. Contact LENTON for additional tool recommendations.
Refer to complete installation instructions provided with the product or available at erico.pentair.com prior to commencing installation.
