CertiFlat 8"x8"x16" Riser Block


Sometimes here at CertiFlat we’ve been in a position that we need modular structures or blocks to get our projects held and located, have you ever been there? Trying to weld up some frames but they not only are flat but go vertical or building that car frame project, we are now offering a solution, CertiFlats Riser Blocks. They come in several configurations, please see below and click the link to the perfect sizes.   All RiserBlocks feature the following:
  • CNC Laser Cut for accuracy. 
  • Ultra-Strong 1/4" Thick A36 HRPO Prime Steel
  • Fit 16MM and 5/8" Tooling Holes and Tables
  • Available in Many Sizes and Configurations
  • Very accurate and square (if assembled correctly)
Our RiserBlocks feature the same mounting pattern as our Certiflat tables along with all the accessories so you can use them how you need. These work great for building products of all shapes and sizes or if you need to go vertical with your setup. With our propriety tab and slot engineered design this will basically square themselves.
