BROCKHAGE BRINGS MUCH NEEDED IMPROVEMENT TO THE COMMON AIR WEDGE
The common air wedge for locksmith use has been around for a great many years, but thanks to the folks at Brockhage it has been reborn as a much more useful tool. Air wedges, which are simply air bags in the shape of a wedge, are used to separate the glass window of a vehicle from the door frame, just enough to get lockout tools inserted either down into the door cavity or into the passenger compartment. Up to now, it's been something of a challenge to get these floppy instruments far enough into the tight and narrow space to let them do their work. You almost always had to use a separate plastic wedge (don't try using a metal tool like a screwdriver unless you want to hear a big POP when the window shatters).
Not now that the CDW-10A is on the scene. They've gone and made the old CDW-10 wedge better (and it was one of the best wedges, too). A stiff insert has been added to the bag which makes it far easier to get it started into the very tight space between window and door frame. In worst case scenarios you might still have to use a plastic wedge to get the space a tad wider, but it takes a separation of less than 1/16" to work the stiff edge of the CDW-10A down into the door.
Another improvement is that the surface of this wedge has been textured. This gives it some 'teeth' and helps it stay put after you've pumped it up.
We sell a good many of these air wedges and at this point they're really the only ones I personally recommend, as it my own experience I've had great luck with them.
