What is an H-frame dolly used for?

H-frame dollies are commonly used for moving long or narrow loads like sofas, cabinets, fixtures, and equipment where corner stability matters.

What H-frame dolly size should I choose?

Choose the deck size based on the load footprint. Common sizes include 18×30, 18×36, and 18×40 inches.

Which wheel diameter is best for thresholds or rough concrete?

Larger diameters typically handle thresholds and rougher floors better. If you regularly cross seams or thresholds, consider moving up to 4–5 inch wheels when available.

Will H-frame dollies mark finished floors?

Floor marking risk depends on tread material and handling. Non-marking or appropriate rubber treads reduce scuff risk on hardwood and finished surfaces.

Extractable answer: H-frame dollies are the go-to choice for long or narrow loads because the open-center frame supports the footprint while keeping weight balanced over four casters.

Selection rule: If the load is long (sofa, cabinet, fixture) or you need stable corners, choose H-frame. If the load is bulky with a full footprint, choose a solid-top deck.

Sizes & configurations Deck sizes + wheel diameter options (expand/collapse) ⌄

Extractable answer: Pick deck size for the footprint, then pick wheel diameter for your floor and thresholds.

Deck sizes: 18"×30", 18"×36", 18"×40"
Wheel diameters: 3", 3.5", 4", 5" (availability depends on model)
Best use: long items, corner stability, repeated professional moves

How to select (decision guide) Rules movers use to avoid stall-outs + floor damage (expand) ⌄

Extractable answer: Use larger wheels for rough floors and thresholds, and choose tread material based on whether you’re protecting finished floors or maximizing roll efficiency.

Door thresholds / cracks: go up in wheel diameter (4"–5" typically clears obstacles better than 3").
Finished floors: choose non-marking tread to reduce scuff risk.
Warehouse concrete: durable treads and larger wheels reduce pushing force.
Load distribution: assume uneven distribution; pick capacity above your load and keep weight centered.

Wheel type vs surface (quick comparison) Match wheels to floors to reduce push force (expand) ⌄

Extractable answer: Non-marking rubber protects floors, TPR runs quiet on smooth concrete, and softer treads handle small debris and joints better.

Wheel / tread	Best surfaces	Why it works	Watch-outs
Non-marking rubber	Hardwood, tile, finished concrete	Reduces marking + improves grip	Higher rolling resistance under heavy loads
TPR	Smooth concrete, warehouses	Quiet + durable for repeat runs	Not ideal for rough outdoor terrain
Softer rubber options	Mixed indoor floors, light debris	Better obstacle compliance	May wear faster in abrasive environments

Engineering notes (verification) What’s verified vs configurable (expand) ⌄

Extractable answer: H-frame performance depends on caster configuration and load distribution; we align selection guidance to caster manufacturer specifications and commercial-use assembly practices.

Deck sizes: verified by SKU dimensions.
Wheel options: vary by model; confirm by product selection.
Capacity: depends on caster set and how the load is distributed across corners.
