Guardian sliding door double roller with two tabs
Thank you,
Ronnie
Hey, Ronnie! It's tough to tell from just seeing the underside, but this looks like our 81-018. Look over our photos and dimensions and let me know if you agree.
Ttys,
Ronnie
It was my pleasure, Ronnie. I think the 81-018 is a promising match, there aren't many rollers made in this particular style.
However, there is one detail you should keep an eye out for when you get your hands on this again. Make sure that the two screw tabs on either side are completely flush with the housing. There is an older version of the 81-018 that I see every so often that has those tabs significantly lower than the housing. That part hasn't been made in many years and the 81-018 cannot be used as a replacement. I'm afraid we don't have anything that can replace that, to be honest, so make sure to note that detail.
Looking more closely at your photo after I typed all that, your tabs do appear to be flush with the housing. But you should definitely still check just to be 110% sure. You don't want to take any chances.
