The Sentri range of Black Site and Vanboxes has build up a considerable reputation over the last 10 years from a standing start to being a leading, repected and recognised name throughout the industry at home and abroad. Their brand new range of Sentriboxes are now available for immediate delivery nationwide and have even more security features. For example, anti-jemmy bars, hydraulic arms and a pair of double throw deadlocks operated by Eurocylinders on every box.
