Procedures, Storage, Installation, and Additional Information

Adherence to the following procedures is required for our 15 year warranty.

FLOAT STORAGE:
• Our dock floats are shipped upside down with the plug hole facing downward. We
recommend floats remain face down in storage.
• Do not store floats with vent plugs inserted in areas of direct sunlight or extreme temperatures.
• Do not stack floats in excess of ten feet high.
• Dropping the float may result in damage to the corners and flanges.

VENT PLUGS:
• Vent plugs are not to be installed until the float is ready to be installed and or used.
• Prior to vent plug insertion, ensure any water that entered the float through the vent hole is drained
completely.
• Apply silicone or pipe sealer on vent plug prior to installation to keep the float watertight.
• A 5/16” Allen wrench is needed to install the vent plug.
• Thread the vent plug into the float drum until the top of the plug is level with the top of the float.

DOCK FRAME SUPPORT:
• Both the sides and ends of the float must be supported by the dock frame.
• The minimum frame support of the float must be every 48” x 48”, or sixteen square feet.

FLOAT ATTACHMENT:
• All mounting slots of float must be bolted or lagged to the frame if the dock is exposed to tidal
changes or strong wave action.
• A minimum of four mounting slots must be used to attach the float to the dock frame for any float
four feet in length or less.
• Floats greater than four feet in length must be attached using all mounting slots along the sides of the
float and at least one hole or slot in every corner.
• Attachment requires a minimum of 3/8” bolts, lag screws or float clips.
• Bolts, lag screws, float clips, washers and lock nuts must be galvanized or stainless steel.

DOCK INSTALLATION AND REMOVAL:
• When installing or removing a dock section with float installed, lift each section – Do not slide floats.
• In areas of severe ice movement, docks must be removed during winter months.
