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.


















The Tandem Low Height is PH Casters' compact twin-wheel medical caster with reduced overall height. Designed for hospital bed chassis, lift platforms, integrated dollies, and compact rehabilitation equipment where vertical clearance is constrained but full twin-wheel capacity is still required. 100mm and 125mm wheel diameters across Swivel, Total-Lock, Directional-Lock, and With-Brake configurations.
The Tandem Low Height shares the twin-wheel architecture of the Tandem Standard Height series but is built with a reduced overall mounting height. This makes it the right choice for hospital bed chassis with constrained ceiling under the frame, integrated lift platforms, compact dolly applications, and rehab beds that prioritize a low patient-transfer height. Mount options include plate (M05) and 13mm bolt-hole (H05). All configurations carry the same 275 lb per-caster rating and the same Swivel / Total-Lock / Directional-Lock / With-Brake variants as the Standard Height series.
Choose Tandem Low Height when you need twin-wheel capacity but the equipment chassis has constrained vertical clearance under the frame. For typical hospital bed and trolley applications with normal mounting clearance, use Tandem Standard Height instead.
100-125mm Total-Lock for beds with constrained vertical clearance under the frame.
Tandem Low for sit-to-stand lift platforms and patient transfer aids with low mounting envelopes.
Compact dollies and transfer carts where the caster envelope must fit under the chassis without raising the deck height.
Therapy and rehabilitation beds prioritizing low patient-transfer height for accessibility.
Compact exam table chassis with constrained mounting clearance.
Low-profile specialty hospital carts where standard-height twin-wheel casters won't fit.
CasterHQ operates Caster Doctor, an on-site service for Dallas-Fort Worth metroplex hospitals, surgery centers, long-term care, and rehabilitation facilities. Our technicians audit your equipment, match the correct Tandem Low Height variant per device, quote parts + labor, and install on-site.

Choose Low Height when your equipment chassis has constrained vertical clearance under the frame and a standard-height twin-wheel caster won't fit. Choose Standard Height for typical hospital bed and trolley applications with normal mounting clearance.
