- 5 of 5 Perfect May 27th, 2026
by Daniel from Monrovia, CABlum tandem is the best slider I even used. It looks difficult to install but once you understand it, it become very simple and easy to install. Likewise it easy to remove. I’ll never use any other slider again.

Ordered the wrong parts and they were great fixing my issue. Will be my go to from now till on
- 5 of 5 | June 19th, 2026
Good service. Had parts i needed in couple of days.
- 5 of 5 | June 19th, 2026
Tried finding the hinges elsewhere. Found them right away. Perfect match.
- 4 of 5 | June 18th, 2026
I was able to find the exact hinge needed to replace broken hidden Soss hinges in a Martha Washington cabinet. The price was reasonable. It did take a while to ship out (ordered May 15, shipping notice June 2) but then arrived quickly once shipped.
- 5 of 5 | June 18th, 2026
I have looked and looked for replacement parts for my cabinets and was about to give up hope, but thankfully they had the exact parts I needed. They arrived quickly, reasonably priced and I am thrilled.
