When connecting up your window opener and operator the conduit lead that runs between them will need to be securely held in place at both ends. Adding a groove to the end of the conduit means that it can be firmly gripped and clamped in place - so it won't become loose or get pulled out and damage the connection between operator and opener.
At Rocburn we offer the T900 conduit grooving tool to make setting up your conduit easy. The tool allows you to add the groove needed to secure the conduit. It's best used along with a conduit bending tool as you put your length on conduit in place.
