Dottie D50S Bolt, 1-1/2" Piece Knockout Seal

Protect electrical boxes and equipment with the Dottie D50S 1-1/2" knockout seal bolt — a simple, reliable solution for covering exposed knockouts in metal enclosures. Designed as a three-piece knockout seal bolt, this Dottie product installs from either the inside or outside of the box, so technicians can complete jobs faster without rearranging wiring. Constructed from carbon steel and sized for 1-1/2" openings, it offers a secure threaded strap fit that prevents accidental opening and helps maintain enclosure integrity.

This bolt-style seal is ideal for use in security and surveillance installations, network and monitoring cabinets, and general electrical enclosures where protecting wiring and components matters. Sold as a pack of 10 (manufacturer model D50S), it gives contractors and facilities teams the inventory they need for multiple cameras, access-control boxes, or junction panels. Improve safety, reduce installation time, and maintain tidy, tamper-resistant enclosures — add the Dottie D50S knockout seal bolts to your next project kit or order a pack for routine maintenance and new installations.
