Dock Edge Howell 600 Foam-Filled Float

Hi Robert- Thank you for your question. The Dock Edge hardware system is designed for use with 1-1/2″ thick lumber (minimum width 6″). All hardware is mounted with carriage bolts. Always use backer plates or other piece of hardware when bolting through wood along with lock washers. This will eliminate the bolt pulling into or through the wood. This will allow the nuts to become loose and fall off. Proper chaining of a dock is critical. Use proper dock anchors (min 250lbs per anchor) and cross chains. If there is no water fluctuation chains may be pulled taut by having a few people stand on the corner while you tighten chain.Use a piano hinge or other arrangement for decking boards over anchor chain corners for easy access for adjustment. To calculate flotation: Weight of wood and hardware = 5-7lbs per square foot (based on 2 x 6 cedar) Weight of people and furniture = variable Dock with floats should average sinking 20-30% into the water leaving 70-75% remaining floatation for “variable” before dock submerges Dock square footage multiplied by 25 divided by floatation capacity = amount of floats required Dock weight divided by floatation capacity = % dock (float) will sink with no people on it yet Dock weight divided by floatation required x float height = # inches dock (float) will sink with no people on it yet.

Our description states that this float will adjust itself to the height of the water which means they are not easily flooded or destroyed. They can flood if the water is higher than the shore they are anchored down to. So if the water rises well above the shore the floating dock is anchored to, the water will rise above the floats and "flood" them.

This float has a flotation capacity of 600lbs. These do not snap together, unfortunately. Please contact our Technical Team at 1-800-334-6541, for additional assistance.

We do not offer a float of those exact dimensions. If you contact our tech dept at 1-800-334-6541, someone may be able to assist you with alternative sizes to fill your needs.

This float is only 16" high, but (87021) is 2' x 4' and 20" high: http://www.overtons.com/modperl/product/details.cgi?pdesc=Dockmate-Float-Drum-20H-x-2-x-4&i=87021&r=view&from=grid
