The MTL7758+,MTL,MTL7755AC,MTL7758-,MTL7761ac,MTL7761Pac range, with their advanced features, should be regarded as your first choice for all new designs or installations. The recommendations below are based therefore on the MTL7700 range.
Users of MTL700, 4700 or 7000 range can also use the guide because of our consistent numbering policy. Products, in any barrier range, that have the same two last digits (ignoring letters and ‘+’ symbols) will have very similar characteristics, e.g. MTL7787 and MTL787.
