The HMETRK8 is an 8 mm triangle escutcheon key from the HMEIN Series for HME modular freestanding enclosures, used to operate doors fitted with the 8 mm triangle insert.

Standard door hardware on HME enclosures is an escutcheon plate with double bit insert, and a variety of other inserts (and matching keys) are available as alternatives. Once a 8 mm triangle insert is fitted in place of the standard double bit insert, this key operates it.

The series table pairs the HMETRK8 with the HMETRI8 insert, both described as for escutcheon - 8mm triangle. Keeping spare keys for each insert profile in use helps avoid access delays during maintenance.

Hammond lists the part as Escutcheon key - 8mm triangle, short description KEY - 8MM TRIANGLE. It ships in a bag at 0.2 lbs (0.09 kg) and is REACH and RoHS compliant.

The HMEIN Series lists inserts and matching keys for 7 mm and 8 mm square, 6.5 mm, 7 mm and 8 mm triangle, double bit w/3mm pin and standard double bit profiles, plus a slot coin proof insert and a non-locking insert for the HMEHLKL lift handle, so profiles can be chosen per cabinet. For purchasing and inventory records, the HMETRK8 is identified by UPC 623980051758 and UNSPSC code 39121321.
