West System 810 fillable (empty) caulking tube is designed for use with a standard caulking gun.  It is great for injecting large amounts of epoxy, laying a lengthy bead of epoxy, making fillets, or injecting epoxy into holes as in hardware bonding, or repairing cracks in concrete.

Tubes can be refilled again after cured epoxy is popped out.  It holds approximately 295 mL (10 oz).
