Reiss mfg R-26 drawer glide
Perhaps you may have some luck going with our 32-030 rear drawer guide as a replacement. Take a look and see if this part will work for you.
Hello! We have received many reports from customers in the past who said that the 32-030 worked well as a replacement for the old R-26. If you want to give it a shot, you may place an order directly on our site at your convenience.
Thanks for considering us and please let me know if we can be of any further assistance.
There are no holes in the flange, no. The 32-030 also isn't typically used to carry the full weight of a drawer like that; they're explicitly meant for undermount track applications. It sounds like someone might have used it as a repair part for your drawer in error at some point in the past, and the guide reached its breaking point.
As for screw size, we recommend a #6.
