SuperGrip™ Grates

RADIUS 

Sections of UV stabilized PVC grating in 24” long pieces connected end  to  end  to  accommodate  the  length  of  the  radius  sections.  The width  is  in multiples of one  inch,  from 6”  to 18” wide.   For sizes  6‐10”  there  shall  be  cross  supports  spaced  at  6”  (max) intervals around the perimeter to span the gutter opening, and to accept the parallel bars. Place supports at 4” OC for sizes 11‐18”.  The  cross  supports are designed  to maintain  the  space between the  pieces  not  to  exceed  0.375”.    The  parallel  radius  bars  are designed  to attach directly  into  the  straight  sections  for a  clean transition.    Field  bend  radii  12  feet  and  greater.  Radii  between 12’‐5’ must be factory bent and field installed. Not recommended for radii smaller than 5’. 

STRAIGHT 

Sections of UV stabilized PVC grating  in on foot  lengths x widths of 6” to  18”  in  one  inch  increments.    Individual  pieces  snap  together  to accommodate  the  length of  the straight sections.   The  top surface of both types of parallel grating shall have a raised diamond ridge design to create good friction, wet or dry, ensuring that decks are safer with rigid, non‐slip comfort underfoot. 

Leading  commercial/competition  pool  designers,  aquatics  consultants and contractors require that equal consideration be given to  each  and  every  element  used  to  create  and  deliver  spectacular, highly functional pool facility. 

To meet the requirements of indoor and outdoor commercial pools, competition pools and the most distinctive pool designs in the aquatics industry, Neptune-Benson has designed a high tech, high performance system of parallel grating, either straight or radius, that follows the contours of any rim-flow pool design. Our Quiet-Flow parallel grating is designed to capture water surge in a matter of inches, and speed flow and disperse rate. The result is a significantly quieter, faster pool without the excessive cost of building sloped or wider gutters.
