Product Information

Single leaf external solid wall lintels are split into three types. MB (Meter Box), TR (Tray) and CH (Channel.) The MB type is generally specified for carrying masonry over the opening formed for a meter box and typically this would be in the outside leaf of an external cavity wall. The TR is very similar in its functionality. The CH type lintel is highly versatile and can be used in conjunction with a concrete lintel and as an alternative to a TF (timber frame) style lintel.

The single leaf lintel is easy to install and features the standard Stressline galvanised finish. These lintels are designed for 100mm or 102mm cavities.



Like all of our steel lintels, the single leaf types are easy to install.

They are suitable for faced brick or block walls.


They can also be manufactured with a SOL (short outer leaf) or a WOL (wide outer leaf) for a variety of applications and uses.



Stressline single leaf steel lintels are designed to support:


  • 100mm external leaf solid blockwork

  • 102mm external leaf brickwork


MB lintels are for meter box applications only. The choice between TR and CH type lintels would be dependent on the load to be carried with the CH having the higher capacity. Occasionally the CH will be used in a timber frame building where, for a particular opening, the normal TF lintel won’t take the required load.
