Durable aluminum tripod head with a leveling bubble and angle adjustment. - Brand: Manfrotto - Model: 229 - Features: Leveling bubble - Adjustment: Angle adjustment dial - Legs: Rubber feet - Features: Durable aluminum - Application: Tripod head It's an older model and heavy, but the stability is outstanding. Also, the screws are 3/8 inch size (the thicker one) on both the head side and the camera side. Please note that it cannot be attached unless the lens tripod mount has a hole of this size. Greasing it up makes it even smoother to use. The strong locking force provides excellent stability. I think it's a product that will make you forget the words "blur," "shake," and "distortion." Thank you for viewing.
