Innovative Hejnar PHOTO FQD1 Quick Release Clamp with Quick Detach Socket

Hejnar PHOTO FQD1 Quick Detach Clamp overview


Up to now we were talking about Quick Release Clamps. Well after the introduction of the Hejnar  Photo FQD1 clamp, it's time we talk about a Quick Release and Quick Detach clamp two in one.

The concept is not new but the FQD1 brings two worlds together. The world of the QD - quick Detach system into the world of Hejanr QR Clamps. Somehow, these two have something in common. Both have been tested for rigidity and durability for many years.

The FQD1 clamp

Manufacturer Specification:
Model:FQD1
Jaw Length:1" (2.54 cm)
Weight:62 gr (2.2 oz)
Center hole:Quick Detach (QD) Socket
Side holes:None
Long Captive Screw Knob:Stops at maximum opening

The innovative Hejnar FQD1 is based on the good old 1" (2.54 cm) Hejnar Photo F60 Quick Release clamp reviewed quite many years ago and as updated in November 2013 with Decimal scales on both jaws. Nonetheless, the clamp maintains the high quality characteristics of all Hejnar QR clamps featuring Tongue in pocket design of the moving jaw guides which guaranty a long term impeccable operation by not allowing dirt and grit entering the clamp interior.

However, what's actually changed from the original is the countersunk and threaded 3/8"-16 center whole, which with some modification now accommodates the Quick Detach socket.
The QD socket utilized is made of steel with ferritic nitrocarburizing treatment, making durable and its surface wear-resistant.

The bottom side is also different from the original, been flat and without the usual alignment holes, grooves etc. Just the hollowed part on the front which serves only for weight elimination.

The FQD1 features the small black hard-anodized, one-piece aluminum knob with the standard by now diamond pattern which has become a point of recognition on all Hejnar QR clamps.



Application

The centered QD socket on the FQD1 is obviously used to attach a standard push-button QD mount. That mount, may well be a QD Sling Swivel which combined with the FQD1 clamp would enable a sling strap to be attached on your camera Arca-Swiss® style body plate or L Bracket.

The QD system has been used for many years by industries around the world including NASA, law enforcement and military agencies. The design inhibits accidental removal, especially when something is hanging from the strap.
Therefore, you may attach your favorite strap to the clamp, then attach the clamp on even your expensive telephoto lens via its Arca style Collar foot plate or Foot Replacement.
