Ceelok held a Sold Secure Product Approval certificate in the Gold Category in BS EN 12051 2004, the European Standard relating to security, durability, safety in use, and fire and corrosion resistance, Administered by the Master Locksmith's Association, was set up by the Police with the help and backing of the Home Office and uses the latest information on criminal methods and tests products under laboratory conditions by duplicating those criminal techniques.

Ceelok has been licensed (2004) under the Secured by Design initiative managed and promoted by the Association of Chief Police Officers and backed by the Home Office Crime Reduction Unit. Ceelok is a simply designed door security bolt which is actually stronger than sophisticated and expensive locks, bolts or door chains.

• Installed in minutes using only a screw-driver.
• Fits both left and right hand opening doors.
• Quick to operate in an emergency.
• Suitable for those with limited mobility - simple large D-Loop mechanism can be easily operated with the palm or  side of the hand as with the fingers.
• Anti slide-back pin prevents any movement of the bolt resulting from vibration or an accidental knock.
• Ceelok's locking plate secures to the INSIDE of the frame - so when the door is closed the screwheads are sealed by the door itself, making it virtually impossible to force them out.
