is this model locking - the clamp locks in squeezed position?

A Yakima SKS Lock Core fits into the red knob on the claw. That locks the bike to the Yakima rack (yes, in the squeezed position). But only thumbwheels secure the rack to the car: a thief with a working set of thumbs could make off with your unridable, rack-attached bike. There is also a Yakima Accessory Lock Housing that may or may not lock the rack to your bars (could replace thumbwheel with lockable nut housing). Check with Yakima on that. I don't use either. I have a cable & padlock I loop through the bikes and my factory roof rack. And I don't leave bikes unattended, other than a lunch stop to or from my destination. Check out Yakima security page.

The unit you get from Amazon does have a locking mechanism..... it is the arm that you see in the top left of the picture.

No i always lock mine. I think it tells you to do that in the instructions.

I think the press you have may be defective. My press does not wiggle at all. It is solid. I hope this helps. :-)

mine fit just right, not a lock fit. perhaps you may have had a slight defect.

I agree with the other answer - it only locks when it's in the upright position.

Got mine earlier this week and while I'm still trying it out, the lock does work for me. After a few days of shaving vibration, it loosened a bit, but that was solved by just pushing it fully back in the locked direction. Sounds like yours is malfunctioning.

I found shimmying the clamps up, first one side then the other, works best. Kind of a pain, but once it is in, it is locked in!

I haven't had this problem. I've been using mine for awhile, and all clamps cinch down nice and tight. The only ones that I've found need extra tight cinching, are the two handles as there's more leverage at work there. I actually was suspect that it would work as well as it does as the price was way below rigs from Red Rock Micro and Zacuto. But I've been pleasantly surprised. Something sounds wrong with yours and you may consider exchanging it.

I'd say it's a defective unit. If you can't tighten it up, I'd get another one. Both mine are tight and work great.

Actually, there must be something extraordinary taking place. I am using the clamp as you mentioned and it is a relatively tight fit without a lot of wobble. There is supposed to be a brass/bronze bushing in the hole in the clamp, if it is no there then it would be very wobbly.Hope this helps.

I have had no problem with locking. But it sometimes show incorrect length in the display.

Hi Susan G. Are you able to turn the knob far enough to have the retaining clamp down at all on the screen? The knobs have a ramped underside that aply more pressure the farther you turn them. I didn't try changing the retainers around to see if the clamp force changed any but they should be on so that the "center" edge, that acts as spring pressure, is the same as the rear one in the direction it faces...it's hard to explain...sorry. Hope this helps!

Yes, it should automatically lock when u put it in the on position-if it doesnt just be sure u have it completely switched in the on position or it may have a defective switch.

Yes it locks in both the in position and when extended. Just make sure the lock handle does not contact anything. I had to notch the trim that on bumps would hit the lock handle and unlock the slide (handle was resting on the trim). After I notched the trim all was good. Great for upgrading to a flat screen in the RV.

It does not lock into position and is only balanced by the weights. I took another look at it and you may be able to rig something up to lock it but "out of the box" so to speak it does not lock.

Yes, It locks in the up and down position. There are two safety clips on the release bar that must be moved before you can press the release bar
