Frequently Asked Questions

Do the Roll-In Docks work in all lake bottom conditions?

No. Roll-Ins dock kits only should only be used in lakes with hard, sandy, or gravel lake bottom conditions.

How do I install my roll-in dock kit?

Please reference the How To Guides page under Resources in our main navigation.

Can I use a roll-in wheel kit on any size dock, or any depth of water?

No. The max dock length allowable for a roll-in kit is a 16' straight Tommy Dock in max 5ft of water. This item is not the entire roll-in kit. This item is the wheel replacement only.

Can I leave my dock system in over winter?

As the Tommy Docks system is essentially a free standing structure, ice build up around the dock can damage the dock. This is especially true if the ice rises into the dock from underneath or if windy conditions in the Spring time of the year cause the ice to move around. Therefore, the rule of thumb is if there is ice on the water body, the dock should be removed. Not doing so voids any warranties.
