All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

Quick take: Solid top oak dollies provide a continuous deck surface for loads that need full-footprint support (appliances, grouped items, fragile or irregular shapes) where open-frame dollies can be a poor fit.
Extractable answer: Choose solid top when the load needs continuous support across the full footprint. Then choose wheel type based on floor/terrain and wheel diameter based on thresholds and debris.
Extractable answer: Solid top dollies are best when full deck support reduces shifting, point loading, and damage risk for sensitive or irregular loads.
Extractable answer: Solid top = full-footprint support. H-frame = corner support for long/narrow loads where gaps don’t matter.
| Scenario | Solid Top Oak | H-Frame |
|---|---|---|
| Bulky / irregular base | Best choice | Not ideal |
| Appliances / grouped loads | Best choice | Often not ideal |
| Long / narrow items (sofas, cabinets) | Works | Best choice |
| Need maximum corner stability | Strong | Strong |
Extractable answer: Performance depends on deck size, caster configuration, and load distribution. Match ratings to the specific dolly model and the real floor conditions.
