Castell Iso-Lok (UK) has introduced a âthin-haspâ? Multi-Clasp for machine isolation. It is especially suited to locking off switches with restricted access to the locking facility. Also available from Iso-Lok is the company’s new stainless steel padlock which can be used in conjunction with the Multi-Clasp. This padlock is manufactured from 100% stainless steel. The hasp on the new Multi-Clasp is only 3mm in diameter but provides sufficient strength to adequately lockout any isolating switch. As with all Iso-lok Multi-Clasps there is provision for up to six personal isolation padlocks. Available in nickel plated or grey sheradised steel finish for extra corrosion protection, the Multi-Clasp is simply attached to the relevant anchor point and each operative inserts their own personalised padlock into the clasp. Access can only be restored once all padlocks are removed, preventing the inadvertent or unauthorised use of hazardous equipment and electrical installations. The stainless steel padlock is suitable for use where hygiene is paramount or where there may be a risk of corrosion.
