Dust bags designed for the Lägler Hummel floor sander featuring a zipper and elastic neck. These bags typically measure approximately 19" x 26" to 19" x 30", allowing for significant dust capacity before needing emptying. The elastic neck facilitates a secure fit on the sander's dust port, often used in conjunction with a bag clamp for added stability, while the zipper allows for easy emptying without removing the bag from the machine.
