Vinyl Lock-in Winter Covers are made out of a vinyl material similar to the material of pool liners with a standard bead design. In order to purchase a vinyl lock-in winter cover, we must first measure and confirm the dimensions of your pool as most of the covers will be custom-made. Before reaching out, please confirm that your pool has the second (top) channel around the coping to ensure it qualifies for this type of cover. The second coping channel receives the bead of the cover to lock the cover into the coping, which covers the pool and protects it over the winter. As a bonus, we are proud to say that our lock-in covers are all Canadian-made!

The Boldt team left my place with no garbage and neat. Jay answered all my questions and let me know what was going on step by step. I will definitely call Bolt pools for my next pool service.
Boldt Pools & Spas St.CatharinesMatt and Tanner were very professional, explained the job and conducted an excellent demonstration on how to use the pump and timer. They were also very detailed to how this variable speed pump will save our energy cost and also how to clean the pool better and use less chemicals. Great work guys, thank you!
