SlapKlatz is a Danish drum accessory brand founded in 2009 by Gunnar Kristiansen, operating out of Ejby, Denmark under the parent company gKompagny. The brand specializes in drum dampening gels — small, reusable adhesive pieces that drummers place on drumheads and cymbals to tame unwanted ring and overtones without sacrificing tone or playing feel, offering an alternative to gaffer tape and moongel-style solutions.

The core product line includes the entry-level SlapKlatz MINI and the professional-grade SlapKlatz PRO dampeners, which come in assorted sizes for use on snares, toms, kicks, and cymbals. The company has also released variants such as the SlapKlatz PRO Blue Ice edition and offers refill packs (Refillz) for existing customers. Products are distributed in nearly 40 countries through a network of drum shops and dealers.

SlapKlatz has built an artist roster that includes drummers such as John JR Robinson, Benny Greb, and Anika Nilles. The brand is widely known within the drumming community as a go-to dampening solution and is regularly reviewed by drum-focused outlets and YouTube channels.

SlapKlatz has 2 products cataloged on Equipboard, including Drum Set Accessories and Drum Hardware Parts. Their gear is featured by 1 artist, with the strongest followings in Pop, Folk, World, & Country, and Funk / Soul. Notable users include Anika Nilles.
