Marshalltown SeamSlammer Drywall Taper
The Marshalltown SeamSlammer™ Drywall Taper (5301) is a pro‑grade taping banjo engineered for fast, clean, and controlled drywall tape application. Designed to dramatically speed up taping while reducing mess, the SeamSlammer features a thumbscrew mud‑flow adjustment, allowing installers to fine‑tune the exact amount of compound dispensed onto the tape—ensuring consistent coverage with every pull.
Its durable wood handle and adjustable shoulder strap provide all‑day comfort and proper weight distribution for long taping runs. The tool accommodates a full 500‑ft roll of tape, making it ideal for large drywall installations and high‑volume production work. A thoughtfully engineered bulkhead design separates the tape roll from the mud chamber, keeping the tape dry and preventing clogs, slippage, or soggy tape—common issues in lesser tapers.
Replacement parts and blades are readily available, extending the service life of the tool and ensuring reliable performance year after year. Whether you're a professional drywaller or a renovation contractor, the SeamSlammer delivers the speed, consistency, and control needed for a high‑quality taping finish.
