The Newborn FP-05 metal follow plate has a neoprene seal for helping to load Newborn Brothers bulk caulking gun models and can be used with 5-gallon straight or tapered buckets of caulk (sold separately). The follow plate is inserted into a bucket of caulk and forms an air-tight seal, allowing the caulking gun to suck up the caulk. It measures 12" in diameter with seal.

Newborn Brothers manufactures dispensers and accessories for use with sealants and adhesives. The company, founded in 1974, is headquartered in Jessup, MD.
