Split Box Ratcheting Wrenches

How do you get a box end wrench around a compression fitting? Unless you want to leave the wrench in place for the next guy, you’ll want a tool like one of Astro Pneumatic’s split box ratcheting wrenches.

Astro Pneumatics claims their wrenches allow you the access of an open-ended wrench while giving you the convenience of a ratcheting box-end wrench. They construct the heads of the wrenches from chrome moly steel, a steel alloy with chrome and molybdenum, for strength.

If you feel like getting sea-sick, by all means check out their instructional video. Don’t get me wrong — I love when companies shoot videos about how to use their products, but it seems to me that it might be worth the money to hire somebody who’s actually held a video camera before.

The wrenches come in a seven-piece Metric set, which includes 10mm, 12mm, 13mm, 14mm, 17mm, and 22mm wrenches — for some reason they only sell these wrenches in Metric. Pricing for the set starts in the neighborhood of $80.
