Manner casters are Finnish-built medical and equipment casters from the Colson Group, engineered for hospital beds, rehabilitation equipment, surgical carts, institutional kitchens, and clean-environment trolleys. The maintenance-free polyamide construction resists corrosion under hospital wipe-down protocols, and the total-stop foot pedal locks both swivel and wheel in one motion for predictable immobilization. CasterHQ stocks the full Tango (single-wheel, 75-125 mm) and Twist (twin-wheel, 125 mm) range in our Mansfield, Texas warehouse for 3-5 day shipping — no overseas lead time.
Manner casters are precision-engineered medical and equipment casters manufactured in Hanko, Finland by Manner Oy (Mannerin Konepaja Ab), a Colson Group company. The product family centers on two flagship series: the Tango single-wheel medical caster (75-125 mm, 70-100 kg per caster) and the Twist twin-wheel medical caster (125 mm, 125 kg per caster). Both are built with glass-fibre-reinforced polyamide forks and hubs that resist corrosion under repeated hospital disinfectant exposure. Stainless steel, conductive (ESD-safe), and non-magnetic (MRI-environment compatible) variants are produced for specialty healthcare applications.
Versatile single-wheel medical caster with red total-stop brake pedal. Glass-fibre polyamide construction, maintenance-free, easy to clean. 75-125 mm wheel diameter, 70-100 kg per caster (155-220 lb).
Heavy-duty twin-wheel medical caster with intuitive brake pedal that visually indicates lock status. 125 mm wheel, 125 kg per caster (275 lb), available in two height profiles. Total-stop, directional-lock, and plain swivel variants.
Match the wheel diameter to your equipment's clearance, the load capacity to per-caster weight plus a 30% safety margin, and the variant (standard / conductive / non-magnetic / stainless) to your facility's regulatory environment.

Non-magnetic Tango variant for MRI-compatible carts, IV stands, and imaging accessories. Zero ferrous content prevents field distortion and projectile risk.
Tango 100 mm on shower chairs, transfer aids, mobility devices, and parallel bars. Floor-protective rubber tread, quiet rolling on vinyl and polished concrete.
Stainless Tango variant for autoclave-adjacent and aggressive-chemical environments. NSF and food-service compatible. Serving trolleys, dietary carts, food prep equipment.
Twist directional-lock variant for predictable straight-line tracking on procedure room rails. Two height options match a wide range of equipment chassis designs.
CasterHQ operates Caster Doctor, a local DFW-area service that visits your hospital, surgery center, long-term care, or rehabilitation facility, audits every wheeled device (beds, trolleys, lifts, IV stands, crash carts), recommends the right Manner replacement, quotes the swap, and installs the new casters on-site. One vendor, one work order, full turnkey replacement.
"When facilities call us asking why their existing metal-fork casters are corroding under wipe-down with quaternary ammonium disinfectants, we move them to Manner. The glass-fibre polyamide doesn't have a metal-on-metal pivot to oxidize. We've replaced thousands of these in DFW hospitals over the years and the polyamide fork outlives the original by a multiple. For OEM bed and lift builds, Twist's twin-wheel design with the total-stop pedal is what we spec by default — the lock indicator on the pedal actually tells nursing staff at a glance whether the brake is engaged, which is a real safety win on a busy floor."
Yes. CasterHQ is an authorized US distributor and stocks the full Tango and Twist range in our Mansfield, Texas warehouse. Standard SKUs ship in 3-5 business days from order placement. Custom configurations (special colors, non-standard tread compounds, large-volume OEM builds) ship from Manner's factory in Hanko, Finland with a 4-8 week lead time.
Tango is a single-wheel medical caster (75-125 mm) rated to 70-100 kg per caster, used on shower chairs, rehab equipment, hospital furniture, kitchen carts, and shop equipment. Twist is a twin-wheel medical caster (125 mm) rated to 125 kg per caster, used on hospital beds, treatment chairs, patient lifts, and hospital trolleys. The Twist's brake pedal also includes a visual lock-status indicator that's particularly useful for nursing staff.
Yes. Conductive (ESD-safe) variants exist across both Tango and Twist series for operating rooms, electronics-sensitive carts, and ESD-protected workstations. Non-magnetic variants for MRI-environment compatibility are produced primarily in the Tango series. Stainless steel variants are available in both series for autoclave-adjacent and aggressive-chemical environments. Specify the variant requirement when you submit your RFQ.
Manner casters are configured to the application — mounting (bolt hole, plate, threaded stem), variant (standard / conductive / non-magnetic / stainless), brake type, and freight class all affect the landed cost. Quoting by configuration gives procurement teams an accurate total cost (unit + freight + lead time) up front and prevents specification mismatches that result in returns.
