We would like to give some information about using, or not using washers on our units. The cable eyes on the units that don't have washers, instead have a .010" "step" 
(please, see picture) on both sides of the cable eye (steel head) near the axle, as you can see in the photo. You can see this on your cams if you look closely. The cable eye washers are essentially an integral feature of the cable eye itself.
There is no difference in operation or strength regarding this minor change in the piece.
The washers are used to adjust the amount of end clearance on the axle for units with the steps on the sides of the cable eye. Actually, this "step" on the steel head gives us more "flexibility" when we assembling units. If there is room on the axle, we can put washers next to steel head, but if there is not extra room, we do not use washers. This is not an assembling mistake, because steel head already has "step" which works as a washer.

CCH conducted a drop test of Blue alien (3/8). This test used 186 lb drop weight with a 216 lb. counter weight and generated a force of 1,714 lbs. After the test, blue alien was undamaged except for indentations on the cam lobes and possible slight bending of axle and still operated OK.

CCH conducted a drop test of Yellow alien (3/4). This test used 186 lb drop weight with a 216 lb. counter weight and generated a force of 1,609 lbs. After the test yellow alien was undamaged except for indentations on the cam lobes and still operated OK.

CCH conducted another drop test today on the same cable assembly that was used in the previous 4 drops.
Drop # 5 used 188. lb drop weight with a 216 lb. counter weight and generated a force of 6.92587 kN (1,557 lbs.)

CCH conducted it's first drop tests on a 5/32" cable assembly this weekend with their new Drop Test Tower.
Of the 4 drops (all with the same cable assembly),
Drop # 3 used a 143 lb drop weight with a 180 lb. counter weight and generated a force of 6.17857 kN (1,389 lbs.)
Drop # 4 used a 153 lb drop weight with a 180 lb. counter weight and generated a force of 6.35205 kN (1,428 lbs.)
Please follow these links to view the video of Drop # 3 and Drop # 4
Note: Cable assemblies used for these tests are randomly picked from production.

The UIAA standard for testing frictional anchors(cams) is EN12276. All certification labs test cams to these standards. Testing an Alien by threading a cord under the cams and then applying force is not a valid test and it doesn't simulate use of the cam in a placement. In use, the cable eye can pivot in the direction of the force and also allow the cable stem to take the flex over its entire length With a cord under the cams and around the cable eye, the eye is twisted so that all the bending
force is located at just one point: the base of the cable eye. This places undue stress at one point and can cause premature breakage, similar to placing the stem over an edge.

To assure that tests made at CCH are accurate, we had our strain gage certified by Mountain Scales in Denver on May 22, 2007.
It was reading 50 lbs over at 2000 lbs,(25 lbs at 1000 lbs) but its now exactly on. A 3/4" Alien is rated at 2700 lbs in a straight pull, at 50%
cam closure or more. The cable on a 3/4 Alien will break at maximum load. However a sharp edge or application of the load in a fall
at an angle to the cable eye can damage the stem or cause it to break at less than 2700 lbs. Use additional runners to help prevent
walking or movement of the cam when climbing past it.

CCH is glad to test Aliens when they are sent to us. If you would like us to inspect your Aliens
send them to us at CCH 115 E Lyon St, Laramie WY 82072.
We are now sending sample test cables to a lab in Denver for tensile strength testing to assure that their results agree with ours. They use an Instron testing machine.
CCH is starting an ISO certification program with TUV. We will give updates on this process.
Its been over a month since the Souders Crack incident. No report has been issued from a metallurgist
that we are aware of. Only analysis of the piece by a lab can begin to answer all the questions
and speculation that exist, we hope a report will be issued soon.
April 27, 2007
It has been recently reported to CCH that the main cable broke on an Alien. We were e-mailed photos
of the cam, however it isn't possible to make any conclusions from a photograph. We have asked the individual to forward the cam to a certified metallurgist for analysis, as of today April 27th, 2007 it has not yet been received by the lab. We will post the results as soon as we receive them from the metallurgist.
