Figure 1: Dock Freeboard

• 50-Series Dock Frame o Rectangular aluminum extrusion o Measures 6.06” high by 3.77” wide o Weight of 3.69lb/lineal foot o Track in top surface of extrusion to allow for bolting accessories such as cleats (movable) and an external diverter plate to the top perimeter of dock.

o Channel on side of dock to allow for the attachment of “D” style rub rail.

Reference Figure 2.

Figure 2: Framing Detail

• All framing components to be Marine Grade 6061 or 6063 Aluminum.

• Fasteners are to be stainless steel

• All flotation is to be plastic encapsulated foam.

• Decking to be Gray Composite with a span rating of 24” on center o 5/4” x 6” nominal sizing

• Decking to be attached using the TimberStrong fastening system, meaning there are no fasteners in the deck surface. Reference Figure 3.

o Fastener is to be mechanically attached to each corresponding deck board o Embedment into the deck board is a minimum of 1-inch and located directly over each joist o Attachment at each joist is to be with one #10 stainless steel, self-tapping screw, placed through the black PVC TimberStrong fastener and into the corresponding joist

• Dock-to-Dock connections to have seamless transitions.

o A flat aluminum strip should be used to attach dock sections together. The strip is to be held in place by a bolted connection through the strip and into the 50 series extrusion. Aluminum splice plates should be installed on the vertical face of the docks, under the rub rail.

• A hinge connection is to be provided on the dock closest to the bulkhead for the attachment to the gangway and kayak chute.

o The hinges are to be slid in the slot on the side of the 50 series dock frame.

• Toe kicks should be provided for all open sides

• External pile guides to be fastened to outside channel on floating docks.

Gangway

• All framing components to be Marine Grade 6061 or 6063 Aluminum.

• Fasteners are to be stainless steel

• Flotation is to be plastic encapsulated foam.

o Supplemental flotation is required to be added to the bottom of the gangway to provide a freeboard of 16” to 18” (with no live load present)

• Railing to be located on two sides, at a height of 42-inches.

• An intermediate handrail is to be located at 34-inches.

• Decking to be 12-inch wide, raised rib, knurled aluminum, welded in place.

• Integrated hinges are to be located at the top and bottom of the gangway.

Hinges are to be mechanically attached; welded connections will not be permitted.

o 1 ¼” schedule 40 stainless steel pipe hinge pins with stainless steel hardware

• A 4-inch toe kick should be provided on both sides of gangway.

Bulkhead Mounting Kit

• Aluminum angles with integrated attachment of hinges. Reference Figure 4.

o Hinges are to be mechanically attached; welded connections will not be permitted.

o 1 ¼” schedule 40 pipe hinge pins with stainless steel hardware

• Stainless steel attachment hardware for mounting to existing concrete bulkhead.

o ½” diameter wedge bolts for vertical face.

o 3/8” diameter wedge sleeves and bolts for attachment of top of angle.
