    2.01 General

    A. Provide seismic joint system that incorporates a flexible stainless steel leaf

    spring that is mechanically snap locked into the leaf mount extrusion using no

    fasteners. The system shall be capable of accommodating flexible finish floor

    materials up to 3/8 inch by utilizing an adjustable leaf spring support. The

    system shall show no visible aluminum surfaces except for that of a narrow trim

    05800-2 Allure

    strip extending across the finish floor or wall surface. Throughout the normal

    thermal movement cycle the system shall be capable of vertical displacement

    while providing a smooth transition particularly at walking surfaces between

    opposing floor slabs. (Leaf spring and trim strip profile features that do not

    provide a smooth transition across the joint opening will not be considered).

    B. Furnish Wabo?Allure Model “AFJ” Expansion Control System for interior floors

    as manufactured by Watson Bowman Acme Corp. and as indicated on


    2.02 Components and Materials

    A. Leaf Spring - Material shall conform to A.I.S.I. 301 Stainless Steel. Spring shall

    be tempered and secured to the retainer by a snap, lock fit. Mechanical

    attachments to secure the spring element or rotation of the same during

    movement will not be permitted.

    B. Exposed Trim Strip Extrusion - Material shall conform to properties of ASTM

    B221, Aluminum Alloy 6063-T6. The profile shall exhibit a visible exposed

    finish strip not exceeding 7/8 inch in width and provide a smooth angular

    sloping leg that guides the leaf spring during movement cycles. The profile

    shall be snapped into the base extrusion by appropriate locking features and a

    continuous threaded channel utilizing manufacturers recommended hardware.

    C. Floor Base Extrusion - Material shall conform to properties of ASTM B221,

    Aluminum Alloy 6063-T6. The profile shall exhibit a vertical pillar incorporating

    pre-engineered slot locations to receive the adjustable leaf spring support.

    D. Adjustable Leaf Spring Support - Material shall conform to properties of ASTM

    B221, Aluminum Alloy 6063-T6. The profile shall exhibit a sloped top surface

    with a minimum width of 1/2 inch to receive and support the leaf spring. The

    profile shall have the capability of accommodating flexible finish floor material

    thickness’ ranging from .080” to .375” by its attachment to the corresponding

    slot location on the floor base extrusion.

    E. Leaf Mount Extrusion - Material shall conform to properties of ASTM B221,

    Aluminum Alloy 6063-T6. The profile shall exhibit a semi-closed rectangular

    cavity designed to receive and lock the leaf spring into position without the use

    of fasteners. Profiles that utilize fasteners and promote rotation of the spring

    element will not be permitted.
