Stewart Browne Air Grounding Clamp

ALS10A Aviation Static Bonding Clamp

The Stewart Browne ALS10A is a heavy-duty aluminum grounding clamp engineered specifically for the rigorous demands of aircraft fueling and maintenance operations. Built to comply with Mil-Spec M83413/7-1, this 2 lb. clamp effectively drains static charges to prevent hazardous electrical buildups. Unlike standard grounding pliers, the ALS10A features plated steel jaws that effectively grip rounded and irregular surfaces while also securely holding flat stock without damage, making this clamp ideal for bonding aircraft landing gear or grounding posts to parking area ground points.

Advantages include:

• High-Tension Grip: A plated steel spring delivers approximately 55 lbs. of closing force for a reliable, vibration-resistant connection.
• Precision Jaw Design: Jaws open to 13/16" but maintain a .125" gap when closed to protect thin materials. Jagged edges provide bite on unpainted surfaces, rods, and ground balls.
• Durable Construction: Made in the U.S.A. with rugged cast aluminum housing and the Mil-Spec number cast directly into the handle for easy inspection and compliance verification.
• Versatile Wiring: Features dual Allen set-screw terminals that accommodate up to #6 AWG grounding cable, allowing for secure attachment to either leg of the pliers.
