Overview

Built for reloaders who need a flexible bench setup, this mounting plate assembly makes it easier to move Hornady tools and accessories on and off a workspace without a full teardown. The quick-detach design is well suited to limited bench space, where switching between a press, case trimmer, or other bench-mounted tool needs to be straightforward. Aluminum mounting blocks and cam lock clamps are used to secure the plate and help keep the setup stable while in use. Additional plates are sold separately, and the press and dies shown in the photo are not included.

Considerations & Trade-offs

  • Additional plates are sold separately, so expanding the system means extra purchases beyond the base assembly.
  • The setup is designed around Hornady reloading tools and accessories, which may limit usefulness if your bench equipment is mixed-brand.
  • It is intended for bench-mounted tools, so it adds convenience for swapping equipment but does not replace a dedicated permanent mount for every tool.
  • The product description notes that the press and dies shown in the photo are not included, so the assembly is only one part of the setup.
