9mm Hard Drive Caddy Tray Bracket Rails with Screws for IBM Lenovo Thinkpad Z60 Z60T Z60M Z61 Z61T Z61M W500 W510 W520 W530

Caddy fits super tight against HDD, rubber rails don't even fit caddy properly let alone fit in the PC. They're too short length wise to grip the drive and too tall, instead of griping the HDD they have a several MM gap. If you can somehow get the rails to stay on the caddy long enough to attempt getting it in the PC, it still doesn't fit properly.This is NOT designed for the W520. It's like the rubber rails aren't even designed for the caddy it shipped with (too big).You can get it to fit, but it's extremely tight and took some forcing because there is no extra space whatsoever.The caddy is also extremely tight against a 2.5" drive and has scratched the sides of my drive's housing.So right now I managed to get it to fit inside, but again it took basically forcing it in and pushing the rubber rail in with a flat head screwdriver.Not happy with the fit or the caddy scratching my drive, but it's in.

The caddy was OK but the side rails were too thick to fit the laptop tray slot. They were some type of cheap plastic instead of a rubber material like the original Lenovo tray.

Not fitting Thinkpad W510, and the rapper low in quality and you cannot even install it. Too loose....!!
