By popular request, we've coupled our NP handle clamp with a swivel ball head and Firestore Hard Drive Holder. The NP-L168FS allows you to continuously power the hard drive unit for up to 5 hours when using the NP-L60 NP battery. The swivel ball head rotates 360degrees to position the hard drive unit. The hard drive holder is fabricated from an aluminum alloy, lined with felt, to securely hold the unit while eliminating surface scratching. Requires PT-FS12, 12" P-tap to Firestore Pin Cable.
