Introducing the MT2458 Mechanical Weld-On Thumb, a reliable and robust solution designed to optimize your material handling tasks. Measuring 24" wide by 58" long, this thumb is ideal for machines between 40,000lbs and 54,000lbs and weighs 821lbs. Constructed with four 1 1/2" thick AR400 steel tines assembled in a ladder frame layout and reinforced with gussets, this thumb is built for increased strength and long-lasting durability. The A-Frame link design further enhances the thumb by increasing torsional rigidity, making it a dependable choice for farmers and demolition contractors who require top performance and longevity. Additionally, a greaseable main pin is featured to ensure smooth operation and minimize wear.
The MT2458 features an unparalleled design that sets it apart from the competition. With three adjustable positions at 90, 99, and 110 degrees, you can customize your thumb for the perfect fit and optimal functionality. When not in use, this compact thumb quickly stows away, taking up only 63" of vertical room on your excavator stick and extending just 18" off the stick when stowed, ensuring it won't get in your way when digging.

Please follow these instructions when measuring. You want your "stick to tip" measurement to be as close to the thumb tine length as possible. GENTEC's mounting plates are very narrow so typically there is no problems with the mounting plate (exception is the very smallest class of mini excavator)
Please follow these instructions when installing your thumb.
