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 correspondence from Boldt was excellent with regard to the pool opening schedule and the technicians were very friendly.
Matt & Josh make the dream team of pool technicians! Their knowledge, friendly demeanor, and informative approach left me with the utmost confidence in having my pool closed for the winter. I hope they’ll be available for my spring opening because their expertise is truly unmatched. I highly recommend them and have been totally satisfied […]
Exceptionally professional, knowledgeable, and helpful! I’m extremely satisfied with the service and plan to return for additional work on my pool equipment. Thank you!
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.
