A quick and simple method of creating aspirating smoke detection sampling holes of the correct size.
During installation, all pipework sampling holes can be drilled at 8mm. The self-adhesive quick fix reducers are pre-punched into various hole sizes and can be affixed over the 8mm hole to provide a sampling hole of the correct size.
Once in place, the AST-5-015 (available separately) quick fix sampling point marking tape ensures that the reducers are held in place securely.
Supplied in packs of 10 of a single size.
