Completion of Straight Ramp

Note: Place string line from end of level landing to point where ramp will end in order to determine proper ramp slope.

• Continue hanging modules and note that no gusset is needed between Modules #4 and #5. You will need to use 2x4 cross supports at the junction of #4 and #5.

  

• Gussets are placed after the 1/2" carriage bolts have been inserted and tightened. A 1 1/2" hole is drilled to allow the threaded end of the bolt to pass through the gusset. A 1 1/2" indentation is made in the other gusset for the head of the carriage bolt.

• When all landings and modules are in place, make any adjustments needed to insure the slopes of each section are equal. Install the trimmers, 1/2" carriage bolts, bracing and gussets again making sure that 4x4s are vertical and ramp surface is level.

• Decking can now be installed. Use 10 5/4x6 pieces of decking for every 58" of landing and slope. Due to variations in the size of decking due to moisture content, it is important to lay all 10 boards in place and make sure the gaps between them are equal. Equally spaced gaps are needed for good drainage. "Wet" decking boards will shrink a little to create proper spacing.

Check the end grain of each decking piece. Attach to joist so that the grain is facing down like a rainbow.
