On a BAL flush-floor slide-out, hinged compression rollers and their rubber blocks help the room rise from the drop pan as it retracts. This guide shows the manufacturer's left- and right-hand roller assemblies and identifies the different block sizes. These components are separate from the base rollers used on non-flush-floor wear bars.

Factory compression roller and rubber block drawings
The BAL parts sheet shows both flush-floor compression roller orientations and rubber block sizes. Its service document illustrates how a worn compression block sits under a roller at the ends of the drop pan.

Identify the compression roller and block
| BAL part number | Component |
|---|---|
| P854282L | Left-hand compression roller for flush-floor assembly |
| P854282R | Right-hand compression roller for flush-floor assembly |
| F854728 | 1.5-inch compression block |
| F854730 | 1.88-inch compression block (older catalog number) |
| F854731 | 2.0-inch compression block (older catalog number) |
| F854732 | 1.25-inch compression block (older catalog number) |
| F854733 | 3.0-inch compression block |
| F854734 | 4.0-inch compression block |
| F854735 | 2.5-inch compression block |
Part P854282L is the left-hand roller and P854282R is right-hand. BAL's left/right manufacturer parts catalog distinguishes them even though an older diagram repeats the right-hand wording under both images. Compare the installed bracket orientation and the slide's mechanism label before selecting a side.
NewRVParts currently carries the P854282L compression roller. The right-hand assembly and individual rubber blocks are not linked here without matching store listings.
When the slide struggles to climb out of the drop pan
Worn compression blocks may contribute to a flush-floor room struggling as it retracts onto its main wear bar. BAL's illustrated replacement procedure identifies F854734, the 4.0-inch rubber block, and shows how blocks are installed below the hinged compression rollers.
After replacement, BAL directs technicians to recheck slide-cable tension. Use the ACCU-Slide cable adjustment diagrams for the appropriate mechanism, including double-back arrangements.
Avoid confusing these parts with other roller repairs
The 854303 and 854304 wear-bar assist rollers are for a different repair and are expressly excluded from flush-floor use by their installation sheet. For standard floor rollers, 22324 service replacements and ¾-inch versus ½-inch wear-bar applications, see the BAL floor roller identification guide.
