Bespoke Bracket Angle Support
Ancon MDC Bracket Angle Support Systems can carry over 8 metres of brickwork and accommodate any width of cavity from 50mm in its standard form. The brackets are welded to the angle and the material content of both components is optimised to ensure the most economic solution is designed.
There are several variations of the standard MDC System that allow the support angle to be positioned anywhere from the top of the bracket to a position below the bottom of the bracket.
MDC/R has a reversed angle
MDC/I is an inverted system with the support angle at the top of the bracket
MDC/P has the bracket projecting below the structure
MDC/P/NB has a notched bracket
Modular Brick-Faced Units
Ancon MDC systems can be designed and manufactured to support modular factory made brick-faced units, where brick slips are fixed to either steelwork or precast concrete. The units are simply bolted to the underside of the prefixed support angle.
MDC Nexus XI®
Lightweight, prefabricated Nexus XI® brick-faced units by Ibstock Kevington bolted to MDC angle
MDC with Precast Masonry Unit

For in-situ construction, the MDC system can be designed with stirrups, stitching rods and soffit angles.
Details for Specification and Ordering
Ancon MDC Systems are tailored to suit each contract, and are based on the cavity size at the support and the unfactored masonry load to be carried. Leviat will design an economical configuration of channel, bracket and angle.
Specification is as follows:
MDC/type/cavity/unfactored masonry load
e.g. MDC / R / 75 / 5.6
Leviat will design an Ancon system with a reversed angle to suit a 75mm cavity and carry 5.6kN/metre run of masonry (unfactored).
Some applications demand that the support leg is below the soffit of the structure. Where this is no more than 150mm, this can be specified as a suffix to the standard reference by . . . . . . P projection.
MDC/cavity/unfactored masonry load/projection
e.g. MDC / 125 / 7.2 / P 75
Leviat will design a standard Ancon system to suit a 125mm cavity, carry 7.2kN/m (unfactored), with a bracket projection of 75mm.

Accommodating Cavity Variations
For guidance on accommodating cavity variations please download an information sheet here.
Adjustment is provided in every direction to allow for tolerance in the structural frame. The serrated and slotted face of the bracket allows for vertical adjustment. Cast-in channel will provide virtually unlimited horizontal adjustment; slotted holes in a steel edge member will offer more limited adjustment. Shims can be included between the bracket and the frame up to a maximum thickness of the outside diameter of the fixing bolt, or 16mm, whichever is less. When used, the 3mm thickness of an Ancon Fire-Tested Thermal Break should be taken into account when calculating the maximum shimming allowance for a system.
As an alternative to shims, Ancon Extension Plates can sometimes be used to increase the bearing for the brickwork.
Ancon Extension Plates are designed to be used with Ancon Support Systems. The particular application should be agreed with Leviat technical staff to ensure that both the support system and extension plates are suitable. Contact our Technical Services Team for more information.
These extension plates are pushed onto the leg of the angle with the flat surface on top. They are adjusted until the required amount of extension is achieved, this will be from 5mm to 17mm.
Designed to minimise thermal bridging in masonry cavity walls, the patented Ancon Thermal Windpost (TWP2) from Leviat offers up to an impressive 70% reduction in thermal transmission through the span of the windpost.
Construction industry remains open. Manufacturing at Leviat continues through latest national lockdown.
