Brake Options
 Tread Lock – This adjustable brake can be installed in the field or ordered assembled onto the caster. The toe activated brake features positive engagement via rubber faced plate. Available on all swivel casters except 3-1/4″ diameter and V-Groove models.
 Tech Lock – Constructed of durable, light-weight engineered thermoplastics, this brake is ideally suited for wet or corrosive conditions. The simple toe operation holds heavy loads securely. With an advanced brake pad design, the brake is compatible with a variety of wheel types. The Tech Lock brake provides virtually maintenance-free operation with only two moving parts. The temperature range is -30ºF to +250ºF. Available on all swivel casters except 3-1/4″ diameter, V-Groove, and Swivel Lock models.
 Side Lock – Colson’s 4 Series Side Lock brake design places a positive locking force against the wheel hub to hold loads securely. The larger foot pedal makes the brake easier to operate, provides better foot placement, and can be actuated from either end of the pedal for greater convenience. Available on all swivel roller bearing or one piece Delrin models except 3-1/4″ diameter.
 Total Lock – With a press of the foot, lock both the wheel and swivel in any position. The low angle pedal design makes foot access easy for convenient operation, and the contemporary design features thermoplastic construction to resist rust and corrosion.

 Top Lock – Colson 4 Series forks include a special notch for easy installation of Top Lock brakes. The break is cost effective and provides reliable braking under a variety of operating conditions. Available on 4″, 5″, 6″ and 8″ models except V-Groove.
