142 Power Blocks Product Modification

July 22, 2019

Marathon Special Products is announcing a change in the design of the 142 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.
2. Removed non-functional reliefs on exterior barriers
• Cosmetic feature only, pictured in official product notification as item 2
• Additional material around the end mounting holes for covers and marking strips provides a stronger mounting which minimizes risk of breakage while fastening down covers or marker strips.
3. Increased the center-to-center hole dimensions (A) Item 3 pictured in official product notification by .040” (from 2.436” to 2.476”)
• 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
4. Marker strip slot dimension “B” Item 4 in official product notification, will be increased by 0.010” which will accommodate the increased dimensional changes in the blocks center-to-center hole addressed in Item 3.

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.
