Proven safety track record

Since 1994, more than 1,500 clamps have been used daily in countries including the Netherlands, Germany, Belgium, France, England, Ireland, Sweden, Norway, Spain, Australia and the Baltic States. 

Impossible to open unintentionally

Our clamps have built a proven track record over the years. They are reliable and require little maintenance. The construction clamp can only be locked and unlocked by completing a conscious action. The slab floor is firmly secured in the clamp until you switch the lever from 'locked' to 'unlocked'.
