Top Line Grant 72-034 by-passing door hardware set is a heavy duty sliding door hardware solution designed for professional applications where doors need to pass in front of each other. The 72-034 Series is specified for doors between rooms, closet doors, cabinets, storage walls, and partitions, so one set can support a wide range of interior sliding layouts. It is rated for 3/4 inch thick doors weighing up to 150 lbs, allowing solid, heavier doors to be used without overstressing the hardware. The system provides plus or minus 1/8 inch vertical adjustment, helping fine-tune clearances after the doors are hung. Required headroom is 1-7/8 inch minimum to 2-1/8 inch maximum, giving a defined space to work with when planning framing and trim. The hardware is made by Hettich America Corporation as part of its Top Line Grant line for sliding door hardware.
The 72-034 by-passing door hardware set is engineered around a heavy duty aluminum double I-beam track, so the carriers are shaped for that track profile when mounting doors. Headroom requirements of 1-7/8 inch minimum and 2-1/8 inch maximum define the working cavity from header to top of the door, which guides layout for trim and framing around the opening. The plus or minus 1/8 inch vertical adjustment range, combined with serrations in the apron, lets the installer raise or lower the door slightly after hanging to align reveals and floor clearances. The lock nut then holds that setting, so the vertical position is maintained during long-term operation in closets, room dividers, cabinets, storage walls, and partitions.
The 72-034 Series sliding door hardware is specified for doors between rooms, closet doors, cabinets, storage walls, and partitions, so it works across many interior sliding layouts using by-passing panels. The 3/4 inch thick door specification defines the door construction this hardware is designed to carry, supporting common panel builds for closets and room dividers. A maximum door weight of 150 lbs means the carriers and track interface are tuned for relatively heavy interior doors, letting solid or dense doors run on a controlled system. The headroom range of 1-7/8 inch to 2-1/8 inch sets the cavity needed above the door, which is important when tying this hardware into existing framing, soffits, or cabinet structures. Because it conforms to ANSI/BHMA standards, Grade 1, the hardware aligns with demanding performance criteria often referenced in commercial and higher-traffic residential jobs.
The heavy duty aluminum double I-beam track used with this hardware offers a rigid running surface for the carriers, which helps maintain alignment when doors travel across wider openings. Its jump proof design holds the carriers within the track profile, reducing the chance of a door leaving the track during normal use. Pivoting rocker arms keep consistent track-carrier contact, so each carrier follows the track even when the header has minor variation, supporting smoother movement across the full opening. The ball and socket suspension further compensates for small header misalignment by allowing controlled articulation between the door and carrier, which helps prevent binding at one end of the travel. Serrations in the apron create positive steps for vertical adjustment, so door height can be set incrementally without drift. Once that height is dialed in, the lock nut guarantees permanent positioning, providing a stable setup that holds door reveals. The side mount double ball-bearing wheel carrier distributes load through multiple bearings, which supports quiet running and long service life when doors are opened and closed repeatedly in closets, storage walls, cabinets, and partitions.
