BEST BES-5ECP6 – Frequently Asked Questions

1) Do I need the 6-pin or 7-pin BEST 5E slide cap?
The 5E Series slide cap comes in a 6-pin and a 7-pin version, and they aren't interchangeable. Match it to the pin stack of the cylinder you're servicing: a 6-pin E Series cylinder takes the 6-pin cap, a 7-pin cylinder takes the 7-pin. If you're standardizing a building on one core depth, order the cap that matches that depth so your service stock stays simple.
2) What exactly is a BEST cylinder slide cap and what does it do?
It's the small cap that closes off the plug/housing on a BEST E Series cylinder, holding the pin stack in place so the cylinder turns properly. It is a replacement part, not a cylinder and not a core, so ordering one gets you the cap alone. If the cylinder itself is worn or the keying is wrong, the cap won't fix that.
3) Is there a service manual for rebuilding BEST E Series cylinders?
Yes, BEST publishes an E Series Service Manual, and it's the right reference for disassembly and reassembly sequence when you're replacing the slide cap. Follow it rather than guessing: the cap goes on last and it's what retains the pin stack, so an out-of-order rebuild dumps springs and top pins.
4) Can a maintenance tech replace a BEST cylinder slide cap, or does it need a locksmith?
This is a cylinder-level repair. The cap only comes off with the cylinder apart, which means loose top pins and springs, so it's work for someone who rebuilds cylinders, with the BEST E Series Service Manual on the bench. For a property manager without a keying tech on staff, this is a part you stock for your locksmith rather than a swap you do at the door.
5) Does the BEST 5E slide cap come keyed or with pins included?
No pins, springs, or keying come with it. The slide cap is a single replacement component, so a full cylinder rebuild also needs the pin kit and springs to suit your keyway and bitting. Order those separately when you're refurbishing rather than just repairing a damaged cap.
6) I manage apartments with BEST locks - is the 5E slide cap worth stocking?
For a portfolio running BEST E Series cylinders, yes. It's a residential-application repair part, and caps are what get lost or bent during rekeying, so having both the 6-pin and 7-pin on the shelf keeps a unit turn from stalling on one small piece. Stock the pin count that matches your standard cylinders.
