Sin contexto es difícil traducir y solo queda adivinar.

CONTEXT PLEASE Hi Jose Francisco: Please give us some context. You give us no clue as to where this term appears. To give you an example; drummers use gel pads to muffle the heads on their drums and these gel pads are specifically made to stick to the heads so they won't fall off when the drummer strikes the head. You can "lift the gel pad" and place it wherever you like of the surface of the drumhead.

I hope you will provide us with more specific context so that we can try to give you more accurate suggestions for your translation. - Greetings from Acapulco- eski :))
