It does not release dust, ideal for calculation centers and computer or server rooms.
Very flexible, they adjust to the gaps and spaces between installations.

The hole must be previously cleaned before installation.
• In forged applications, a retention system, for example a metal mesh, must be previously placed at the bottom to hold the pads.
• Place the pads in the hole with the long dimension in the direction of the installations, as if they were bricks (that is, with the vertical joints staggered).
• The pads should be left very tight so as not to leave spaces between the installations.

Pads already installed can be reused, as long as they have not previously suffered the effects of fire.
They can be used for temporary sealing during work. Reinstalling cables is very easy.
