Use of gaskets is necessary to ensure a proper seal in weatherproof applications. The Universal

Gasket is included on all Universal Stopper products and is embedded in the STI factory prior to
shipping. Two 3” gaskets are shipped with the SURFACE mount Universal Stopper, refer to Step 8 in
the installation instructions. Each 3” gasket is intended to be used with the inserts also shipped with
the SURFACE mount Universal Stopper. To install, the insert should first be fitted in place in the correct

the cord into the preformed channel until it overlaps 1/8” of the opposing Mounting Gasket.
