LDO Blind Joint Seal for 2020 Extrusion (20 Pack)

Designed by LDO for use with 2020 aluminum extrusions, the blind joint seal helps maintain a more stable printing environment. It closes off the extrusion channel to prevent gases from escaping during printing, while also limiting outside air from getting in.

Installation works just like a T-nut. Slot one side in first, then press the opposite side into place. Finally, slide the seal along the extrusion channel until it seats at the end. Refer to the product images above for guidance.
