My cousin lives in Radnor, PA, and I am helping her replace broken hardware on sliding bypass closet doors. This is a then-modern-style 1950s custom house with many built-ins, fixtures, and hardware from that period. There are perhaps 18 sliding, bypass closet doors with unusual roller assemblies that hold each door onto a two-track rail mounted on the underside of the top door jamb. We probably need at least ten roller assemblies to replace the broken and missing assemblies presently mounted.
Attached are annotated pictures of the roller assemblies presently installed. The two pictures of removed hardware actually show 1 1/2 sets of hardware, so you can better see the two main pieces of the original assemblies.
I thought one of the distributors I already contacted could provide correct hardware, but they cannot source the parts. Nonetheless, my last attachment is of their catalog page which shows some possible replacement hardware, including part numbers 3-170, 3-171, 3-206, and 3-185, that MIGHT be candidates for my project. As described, the distributor cannot source these parts.
I am not certain how the offset is calculated, but hope the pictures attached to this email help clarify what is needed. The attachment "Hardware offset" is really a question for you. Is the hardware we need properly described as 1/2" offset?
Please let me know what hardware you recommend for this project. I am not sure whether it is best for me to buy two modern roller assemblies and confirm that they work properly, then buy additional hangers to complete the job. If you require any more information, please let me know.
Thank you.
