  • Non-slip grit traction layer
  • Lightweight

  • Grate open area of 48%
  • Grate openings 0.57″ x 1.67″ (1″x2″)

* Load class ratings for entire systems will always be determined by the lowest class within the system. For example, if the channel is rated as a C and the grate is rated as a D, the overall system will be rated as load class C. The same is true should the channel be rated as load class C and the grates are rated as load class A; the system as a whole would be rated as load class A.
