143, 144, and 145 Power Blocks Product Modification

July 22nd, 2019

Marathon Special Products is announcing a change in the design of the 143, 144 and 145 series power blocks. This product change is the result of a tooling modification intended to reduce molding maintenance costs and downtime and provide more valued features.

General Changes:

1. Eliminated all non-functional center holes on the top of the power block interior barriers.
• These holes had no intended function and were not promoted as a design feature of these power blocks. Some utilized them to mount marking strips where they provided a more robust surface area as opposed to the outside top barrier holes, which we have addressed in this design upgrade.
• Elimination of unnecessary locator pins in the mold will improve production efficiency by minimizing mold maintenance and downtime.
• In conjunction with Item 2 above, mounting holes in the exterior barriers have been centered in those barriers. This repositioning results in the increased center-to-center hole dimension providing greater strength and product integrity.

This will be a running change with no variance to the part numbers or ratings. The change will be implemented approximately 8/15/19.

All orders received after the implementation date will have the updated design. Special parts having a 5 digit code after the catalogue part numbers will be included in this update. The 5 digit codes mostly address accessories such as printing, labeling, hardware or packaging needs.
