Rail,20IN,RM413/423

Contrary to the other review, the ones I received do allow for full travel of the chassis. I was able to slide the chassis completely out and gain access to the lid without removing it from the rack or any other issues.

Despite saying these work for the RM413 series, these slides are too short for the RM41300 chassis. They will attach and they slide great, but the travel isn't enough to get the chassis all the way out of the rack so that you can remove the cover. The only way to get the cover off is to remove whatever you have above the chassis in the rack so you can lift up the back of the cover. NOTE: This isn't a problem with the listing here on Amazon, Chenbro's website says these fit the 413, but they don't. I have tried every combination of positions and adjustments to the brackets that hold the rails. There simply isn't enough travel. Two stars because on a chassis they do fit properly they would be decent slides at a good price. But only two because Chenbro says these work on the 413 on the US web site. On the international web site Checbro lists a completely different part number. So, only two stars.
