COMMON APPLICATIONS: Connecting 3-prong clamps, flask clamps, and retort rings to vertical lab stand rods; mounting extension rods and horizontal crossbars to retort stands; assembling multi-level glassware support systems for distillation, reflux, and filtration setups; securing thermometer holders and condenser supports on lab stand rods.

USAGE NOTES: Finger-tighten thumb screws firmly before loading – do not over-torque as this may strip threads. Ensure the rod is fully seated in the channel before tightening. For heavy loads, position the accessory as close to the main vertical rod as possible to minimize the lever arm. Stainless steel version can be rinsed with water after use in corrosive environments.
