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.
A 6" Rigid Tech Lock Model is available: Specially engineered for rigid caster models only, the contemporary design features thermoplastic construction to resist rust and corrosion. A grip ridge for the mechanical lock fastens the Tech Lock brake to the fork.
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. Available on 4", 5", 6" and 8" swivel models except 3-1/4" diameter and V-Groove models.
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.
Foot Activated Swivel Lock -No more back strain from bending down to activate a swivel lock. When the foot pedal is in the “up” position, a stainless steel spring forces a pin into one of the four slots on the swivel fork. This effectively locks the swivel in one of four positions at 90° intervals. To disengage the lock, simply press down on the foot pedal for free swiveling action. It’s that easy! With this innovative product, you can quickly and easily convert swivel casters to rigid casters for straight-line tracking. When you need greater maneuverability, you can quickly convert from the rigid position back to full swivel. Quick. Easy. Less stress and strain. Available on all swivel casters with standard top plate.
Hand Activated Swivel Lock -Swivel locks quickly convert swivel casters to rigid casters for straight-line tracking. A spring-loaded, hand operated plunger is engaged to fit into slots on the swivel raceway. To engage the lock, simply pull out plunger and turn until spring action inserts plunger in notches on raceway. To disengage the lock, simply pull out the plunger and turn so plunger is not inserted in notches on raceway. Available on all swivel casters in Bolt-On or Welded designs.
