Telescopic Tube Locks

 
 

A - Clutch Lock

Aluminum A Style "clutch" lock with knurl for easy turning. This internally threaded 'clutch' includes a split plastic sleeve to tighten on the inside tube when the clutch is turned. Clutch provides trouble-free, secure metal construction. Made in house, these are available in all diameters from 3/8" diameter up to 1-1/2" diameter.
 

B - Split Collar Lock

B Style "Split Collars" are very strong and stiff. They're our strongest lock and are suitable for use with our aluminum tubing or with steel tubing. Features a spring-loaded mechanism and an easy-to-turn 2-finger plastic knob. Available in 1/2" through 1 1/2" diameters. Non-Rotational (NR) compatible 1/2"-1 3/8".
 

C - Cam Lock

C Style internal "Cam" locks are internal and twist to close. This lock is ideal when one handed operation is necessary. Available in 1/2" through 1-1/4" diameters. Not compatible with non-rotational tubing.  Bearing lines are provided between the tube sections.
 

D - Shock Cord

D Style shock cord legs, also known as bungee cords, open easily as they nearly assemble themselves. All sections must be the same diameter. While tubes do not telescope, they do fold compactly. Assembled leg presents itself as a constant diameter.  Available in all diameters.
 

E - Non-Locking

The E Style is telescopic and keeps the inner tube(s) 'captive' so they can't come out. Though this style is non-locking, there are no bearing lines between the sections. Non-rotational compatible.
 

F - Spring Button

F Style spring buttons lock in the tubes at predetermined positions. Non-rotating inside tubes are used to make lining up the spring buttons with the holes automatic. Style F is available from 1/2" to 1-3/8” diameters in 1/8” increments.
 

FA - Spring Button "A" Clutch Lock

FA Style features the A Clutch lock and the F Spring button lock.  This enables the tubes to stop at predetermined positions, while the A Clutch lock eliminates any “play”.   Non-rotating inside tubes are used to make lining up the spring buttons with the holes easy.  Style F is available from 1/2” to 1-3/8” diameters in 1/8” increments.
 

G - Snap Lock

The G Style Snap Lock is in some ways our easiest lock to use.  Simple snap lock system offers effective strength, a clean look and an economy price point.  For critical applications requiring extremely strong locking torque - the B lock is recommended.
 

H - Set Knob

The H Style Set Knob is specially designed to limit marring of the tubes while keeping the inner tube captive. Full metal construction, this is our most expensive lock style and is appropriate for critical applications.
 

Mini Economy Locks

This Mini Lock is simple to operate.  Only two sizes are available.  One for a 5/16" outer tube with a 3/16" inner rod.  Another for a 1/2" outer tube with a 3/8" inner tube.  Stocked each in silver and black, the two size locks do not match style-wise.
 

Swaging

An economical way to form leg ends, so one leg nests into another.  A spring button can be an option.  Swaging features close tolerances and provides great strength.  We are tooled for 5/8", 3/4", and 1-1/4" diameters.
