CoreMaster S321 Commercial Fly Light Glue Boards

Overview

CoreMaster S321 Commercial Fly Light Glue Boards are replacement adhesive boards designed for use with compatible CoreMaster S321 indoor fly light units.

Supplied as a 12-pack, these glue boards support routine fly monitoring and flying insect capture in restaurants, commercial kitchens, food-service areas, retail spaces, warehouses, storage rooms, facility maintenance areas, and professional pest control programs.
