Gullsweep GS-FM Flex MountThe GS-FM Flex Mount is designed for those situations over canvas where one does not want to put a hole in the boat to locate the Gullsweep®.

  • Tough & durable canvas construction
  • All stainless steel hard ware
  • Centre block is 8”x8”x1” giving ridged flat surface
  • Ideal for hard flat areas, cabin tops or hard top boats

The base can be filled with sand which shapes easily over any irregular canvas support members. The important point is to be sure the Gullsweep® centre support pin is vertical to the water.

Gullsweep GS-RK Retainer KitFor those applications when a Gullsweep® could fall off of a non permanent mounting — i.e., GS-FM pulled from a canopy might turn sideways and the Gullsweep® could slide off the centre mounting pin and go over board. Unfortunately, Gullsweeps® do not float.

Slide shrink tubing over lower portion of centre hub. Then, insert straight section of stainless steel bracket between hub and shrink tubing so bend is just above bottom of hub. Apply heat from a hair dryer while turning to shrink tubing tight to hub and bracket. Let cool. (A candle can also be used but do not over heat or let flame touch hub or shrink tube).
Next, push Grommet over centre support pin, Wide end first down to 3″ from the tip (pointed end). Then slide o-ring to top of grommet to further secure.
Slide Hub onto pin and gently pull SS bracket over grommet. Adjust grommet and o-ring position so there Is 1/8” or more clearance above and below grommet. Hub and SS bracket must not touch centre pin or retaining ring.
