Replacement part for heavy mirrored and plywood bottom sliding doors

Thanks for posting. Is the wheel in your roller assembly convex or concave? Convex rollers have a protruding edge that fits into a slotted track; whereas concave rollers have a recessed edge that rides along a raised rail. If your roller is convex, see our 23-081. If it's concave, see our 23-086. If you are uncertain, send pictures of your roller from different angles so we can see. Many thanks.
