Hager 9878CS-72 – Frequently Asked Questions

1) Will the Hager 9878 pocket door track work with a 1-3/4 inch thick door?
Yes, 1-3/4 inch is within range for the 9878 box track set, and that is the standard commercial door thickness. The hardware is sized for doors up to 1-3/4 inches thick, so a typical 1-3/4 inch commercial slab and the lighter interior thicknesses below it both run on the same track. What actually decides your order is weight, not thickness: CS sets carry up to 150 lbs per door and HD sets up to 250 lbs.
2) Should I order the CS or the HD version of the Hager 9878 pocket door hardware?
Weigh the door and pick from that. CS packaged sets are rated to 150 lbs (68 kg) per door, HD sets to 250 lbs (113 kg) per door. A hollow core or light solid core residential-size slab lands well under 150 lbs and takes CS. A solid core commercial slab, a lead-lined door, or anything with glazing is where HD earns its place. One thing to weigh in the decision: the optional soft-close mechanism, part 1-269-8651, is rated only to 150 lbs, so a door heavy enough to need HD is past what soft-close covers.
3) What length Hager 9878 track do I need for a 3 foot pocket door?
A 3 foot door takes the 6 foot track, and a 4 foot door takes the 8 foot. Pocket door track runs roughly double the door width, because the door has to travel its own width clear of the opening plus the pocket. The 9878 comes in 72 inch (1829mm) and 96 inch (2438mm) lengths, ordered as 6' and 8', in both the CS and HD sets.
4) Can I use Hager 9878 parts to repair an existing 9678 pocket door track?
No. Hager states the components between the new and previous versions are non-interchangeable. The 9878CS is the functional equivalent of the older 9678 and the previous 9878CS, so it is the right set to specify when you are replacing one of those, but you replace the assembly, not individual hangers or brackets into old track. If you are servicing an existing 9678 opening, plan on a full set.
5) Is the Hager 9878 pocket door track rated for commercial traffic?
It is a commercial-rated set. The 9878 exceeds 100,000 cycles and meets ANSI/BHMA A156.14 Grade 1 performance requirements, which is the sliding door hardware standard, and Hager classes it as commercial rather than residential. For a property manager or facility buyer standardizing pocket doors across patient rooms, offices, or classrooms, that Grade 1 cycle number is the figure to hold it to.
6) What keeps a pocket door from jumping off the Hager 9878 track?
The track itself. It is extruded aluminum in a jump-proof box style with V-shaped rails, so the wheel assemblies ride captured in the V rather than sitting on a flat surface. That matters on openings that get shoved hard, entrances off corridors, restrooms, exam rooms, where a door coming off the rail is a callback.
7) Do I need to order hangers and brackets separately with the Hager 9878 track?
No, the 9878 ships as a packaged set with the hardware needed for the pocket door installation, so you are choosing capacity (CS or HD) and track length (6' or 8') rather than assembling a parts list. Soft-close is the one thing that is separate: it is an option, part 1-269-8651, and it covers doors up to 150 lbs. Pocket frame studs, the door itself, and the pull are not part of the set.
8) Can I add soft close to a Hager 9878 pocket door later?
Soft close is an option on the 9878 rather than built in, using part 1-269-8651, and it is rated for doors up to 150 lbs. That ceiling is the deciding factor: if the door is heavy enough that you specified an HD set for its 250 lb capacity, it is above what the soft-close mechanism is rated to carry.
9) Is Hager 9878 track hardware suitable for a healthcare or school pocket door?
Yes. Hager lists commercial office, healthcare, educational, retail, multi-tenant residential, industrial, and government buildings as applications for the 9878, and it is backed by a Grade 1 A156.14 rating at over 100,000 cycles. For a facility standardizing across many openings, the practical split is capacity: 150 lb CS sets on light interior slabs, 250 lb HD sets on solid core or glazed doors.
