BEST CD431-2 – Frequently Asked Questions

1) What does the BEST CD431-2 pinning kit actually let me do, and does it work on BEST figure 8 cores?
The CD431-2 is a complete combinating kit for BEST figure 8 cores. It holds the close tolerance pin segments, 22S core springs, core caps, and the tools to do the work: a capping block, two capping pins, an ejector pin, tweezers, two standard keys, and a key gauge. In other words, it is the whole bench setup for rekeying and building BEST figure 8 cores to a new combination, not just a bag of pins.
2) Is the CD431-2 an A2 keying kit, and will it combinate a core cut on a different pinning system?
A2 is the pinning system this kit is built around, and that is the system the pin segments and key gauge are sized for. If your facility is keyed on A2, the CD431-2 covers it. Cores built on another BEST pinning system use different segment lengths, so this kit is not the right box for them.
3) I manage a property with BEST small format cores on the doors. Is this the kit my maintenance staff needs to rekey units in-house?
For a portfolio standardized on BEST figure 8 cores, yes, this is the box that lets you rekey on turnover instead of buying new cores. It carries the pin segments, the 22S springs, and the caps as consumables plus the tools, so the recurring cost per rekey drops to a handful of segments. Two things it does not do: it will not cut keys, and it will not combinate cores on a pinning system other than A2.
4) Do I need a separate tool to get the old core apart, or is that in the kit?
Teardown is covered. The ejector pin knocks the caps and stacks out of the barrels, the tweezers handle the segments and springs, and the capping block with its two capping pins seats fresh caps once you have rebuilt the stack. What you supply is the core itself and cut keys.
5) Can I take a BEST combinating kit out to the job site, or is it a bench-only kit?
It travels. The CD431-2 case is desk drawer size with a secure closure, so it can be carried in any position without the pin segments migrating between compartments. That matters more than it sounds: a kit that dumps its stacks in the truck costs an hour of sorting before you can pin a single core.
6) Why does a BEST pinning kit include a key gauge?
The key gauge is how you verify the cut depths on a key before you pin a core to it. Combinate a stack to a key that is cut off depth and the core either binds or gives you a shear line you did not intend. Gauging first, then pinning, is what keeps a masterkeyed system consistent across a building. The kit also ships with two standard keys to check core operation once it is capped.
7) What are the 22S springs in the BEST CD431-2 for, and do they fit every figure 8 core?
The 22S is the core spring sized for BEST figure 8 cores, and the kit stocks them so you are not reusing tired springs out of a core you just tore down. Reused springs are the usual cause of a core that turns fine on the bench and sticks in the door six months later. Replace them on every rebuild.
8) Is there a BEST reference for figure 8 core keying systems I can check before ordering a combinating kit?
BEST publishes a Key and Core brochure covering its key and core line, and it is the document to check when you are confirming which pinning system your facility runs and which cores you are working with. Get that settled first, because the pinning system determines whether the A2 segments in the CD431-2 are the ones you need.
