Review: Very Pleased! Fit and works perfectly. - I ordered several of these to replace several of the ones in my kitchen that were 13 years old. Some of the drawers were not soft closing properly. They were an exact fit and work perfectly. One of the mounting screw holes in the release mechanism was in a slightly different location but was very easy to move.
Review: Excellent soft close drawer slides - Blum is a bit tricky product to buy... Turns out I did not need to purchase the L brace piece that installs the back end of the slide; found them in the hardware box once I opened them to install. Excellent quality as expected from Blum.

## Questions & Answers

**Q: Are there supposed to be instructions with these?  Product came with nothing.**

**Q: Does this come with the rear mounting brackets?**
A: This listing does not include the optional rear mounting brackets, but if you purchase them from us just send us a message and we will include them for free! Thank you.

### ⭐⭐⭐⭐⭐ Excellent soft close drawer slides

Blum is a bit tricky product to buy... Turns out I did not need to purchase the L brace piece that installs the back end of the slide; found them in the hardware box once I opened them to install. Excellent quality as expected from Blum.

### ⭐ Cheaply made
*by L***I on October 14, 2023*

I opened the box and was very excited to start using it. Howe, the components are made of cheap plastic and broke before I even had a chance to try it. I just shipped it back and received a refund
