What moves the price
For trapped key interlock, the drivers are diameter, length, grade, thread type, corrosion resistance, equipment fitment, tube diameter, steel grade — the spec them differently and the same item lands at either end of the band.
Published US-facing distributor material shows trapped-key interlocks mostly as engineered safety components rather than commodity items, with quoted ranges around $320–$780 per set for trapped-key rotary interlocks and higher-cost solenoid-assisted variants. Pricing moves mainly with the number of stations/keys, mechanical complexity, certification class, and whether the package is custom-mounted or standard catalog hardware; finish, tube/steel spec, and bolt-on vs welded construction also affect fab cost. Realistic sourcing routes are industrial safety distributors, OEM safety-interlock brands, and custom enclosure/machine-guard fabricators; at high volumes, landed-equivalent import pricing can undercut catalog pricing, but true custom engineering and certification usually keep costs elevated
