are the parts that apply the tension to the rails for locking into position plastic, do you get a good grip?

I have the Fotodiox 4-Way Macro Positioning Rails, Tripod mountable, Model XOOOFAVML7 (or X000FAVML7. I cannot determine whether it is "O" or "0".) I do not remember what I payed. The plastic parts, or the parts which seem to be made of plastic, are quite firm and not easy to scratch, using a standard dental scribe. Bottom line is that the entire device operates well and is quite durable. And I do a fair amount of macro type photography. I hope this is of help.

I used a dental scribe to scratch every accessible part of this device (I have three of these Macro Focusing Rails). From what I have been able to see from my scratch tests, it appears that the parts to which you refer are made of a high density, hard plastic. I have had some extensive experience with this device, and I can say that I have always been able to obtain good grips and reliable positioning of photo gear mounted on these Macro Focusing Rails.

Yes they are, and I really like them, they are very smooth and no tension to speak of. When I was shopping for a pair, I read a review on these which said you could adjust the tension by tweaking the screw in the middle for + or -. I have never done this because I liked them right out of the box.

No. These demonstrators are solid plastic. There are no moving parts whatsoever. These are designed for gun handling training ( safe finger position, keeping it pointed in a safe direction, grip etc) not functional ( loading, unloading, trigger pull etc ) D.Waters NRA Certified Instructor CWP Certified Instructor

Absolutely it's a nice rail for the money and works as well as looks great. ..One thing I will tell u is that when u assemble the lock side is to not over tighten the screws they strip quite easily

Absolutely. When you receive the lock, you'll be able to see the recommended places to mount it for maximum grip efficiency an not to interfere with other things you have on the frame

Yes. But are they really necessary? For instance, one product I put them on is Get-a-Grip. The Lock Cylinders stop or deter a possible perpetrators from moving the cable fasteners to access the goods held there, but the Get-a-Grips can be removed quickly by means of their wing nuts from the load racks and the cable fasteners cut at a remote location. And another product the lock cylinders we ere used on was Yakima fold down kayak rack which breaks at the hinges. So it'S your money, and if the cylinder locks g I've you peace of mind, then okay; you got your money'S worth.

no it slips and slides hard to position. the plastic is very stiff. I do not recommend this product

Yes, I have mine set up on round legs as well. It grips really well, and I have not had any problems with it slipping.

Yes, but you'll have to damp it manually, by adjusting the tension. Once you get that set to your preference, you're golden.

Yes. Hard part is taking it apart to put the rails in. But not that hard. Fantastic product!

You will need to adjust the tension in the arms where they pivot. You should be able hold one part of the plastic ring and turn the other. This should loosen/tighten depending on what direction you turn it.Edit - Mine is very smooth and easy to move. Anyone could do it. You may not have to hold part of the plastic but turning that does change the tension.

There's some grippy material on the bottom of the track that does a pretty remarkable job of holding it in place. I've never had it slip while cutting, so never felt the need to buy the special clamps. The system works very well, and I recommend it highly.

Yes, all parts lock in place after they are adjusted to fit your shooting position.

There are set screws in the levers that lock the levers down when tightened. I've only used them on small caliber guns (17 & 22), but with the set screws loose the mounts never loosened on the Picatinney rails.

some plastic,as in grips, clips. balance metal, good solid feel, get extra clips for ease in reloading

Yes, these slid right in. You will have to take off the cover of the rails in the back to slide them in. Directions show the clips to push on the cover to be on the outside of the rail but it is on the inside instead. Pop it off, slide rails in, tighten down and pop it back on. It took about 10 minutes once I figured it out. Be sure to do it on a day that is 60 degrees or better so you don't break the cover.
