1.1 Description
Ceiling-to-Ceiling Knife Edge
The Axiom Indirect Light Cove system is a pre-engineered
lighting solution designed to be used at a ceiling-to-wall
condition or a ceiling-to-ceiling transition and integrate with
Armstrong® acoustical or drywall ceiling systems. The system
consists of an extruded aluminum component and a brakeformed sheet metal component, and is designed to accept
a pre-engineered light manufactured and provided by Axis
Lighting, Litecontrol, or Vode® Lighting.
®
NOTE: Axiom Indirect Light Coves are designed to integrate
with Axis CovePerfekt™, Litecontrol ACOVE15AL, or
Vode® ZipWave™ | LED | 707 light fixtures only.

Component Description:
Acoustical Lay-in Panel
Axiom Indirect Light Coves:
Extruded aluminum face factory assembled with rigid sheet
aluminum to form an indirect light cove with distinct
architectural features, creating a 2-sided light cove at the
wall and at a ceiling-to-ceiling transition. Special bosses are
provided to connect AXTBC T-Bar Connector Clips and
AX4SPLICE splice plates to provide positive attachment with
no visible fasteners. There are two profile designs with varying
elevations and face edge options to accommodate most
situations – a 4" ceiling-to-ceiling cove and a 4" ceiling-to-wall
cove. Both coves have Knife Edge® and Classic trim options.
The ceiling-to-wall cove can be ordered with an 8" or 10"
elevation. The ceiling-to-ceiling cove can be ordered with a
12", 14", 16", 18", or 20" elevation change. Pockets can be
ordered with an optional plenum air slot opening.

the ceiling to ceiling cove. The pre-made factory finished inside
and outside corners are made to match the elevation of your
straight indirect cove sections. Each corner section is 12" by
12" square (dimension taken on the face of the extrusion).

3.2 T-Bar Connector Clips
There are two versions of the T-Bar Connector Clip:
1. AXTBC is used with drywall, lay-in, Tegular, concealed
tile, and installations of Vector® panels that are FULL
SIZED tile. These are INCLUDED with each shipment.
2. AXCCLT45 is used with Axiom® Knife Edge®
Light Cove trim.
3. AX-V-TBC is used with CUT Vector panels. These will
need to be ordered separately.
T-Bar Connector Clips are attached to the suspension system
members using screws supplied by the installer. Framing
screws (#6 x 7/16" or 1/2" long) are typical.
See general installation instructions for alignment of AXTBC,
AXCCLT45, or AX-V-TBC connector clip to the suspension
system member.

Axiom Indirect Light Coves are packaged and delivered in the
quantities ordered. All hardware and instructions for assembly
will be included in the packaging. Custom projects may include
shop drawings as well. Identify all parts listed in the drawings and
verify they are delivered to the site before starting the installation.
Exercise care to protect the finished surfaces of the trim.

3.1 Splice Plates
Steel splice plates are used to align and secure joints between
sections of the light cove trim. Each joint requires a splice plate
at every set of bosses for proper trim alignment. Join straight
sections of cove together using the AX4SPLICEB splice plate.
Splice plates are secured to the trim sections using factoryinstalled setscrews. A 1/8" hex key is included with the hardware.

associated suspension system components.
3.3 Drywall Trim
Drywall bottom trim (AXBTSTR) is added to finish the edges of
5/8" drywall applied to the bottom surface of the Axiom Light
Cove. Drywall trim is fastened using standard drywall screws
applied through the taping flange of the trim into the drywall
suspension system. The trim is finished using standard drywall
materials and techniques.

5.2 Axiom® Connector Clip Options
5.2.1 Prelude® XL® and Suprafine® T-Bar suspension systems
will rest on the lower flange of the light cove. Prelude and
Suprafine suspension systems are used with flat lay-in and
some Tegular applications. For a T-Bar suspension system that
will rest on the lower flange of the Axiom trim, use AXTBC
Connector Clip.
5.3 Silhouette® XL®, Interlude® XL® HRC, and Sonata® XL®
(systems with 5/16" shoulder height) will require the clip to be
modified to be held 1/4" above the light cove flange. Modify
the clip by cutting 1/4" off the bottom of the clip at the score
line. This can be done with a regular pair of snips.
Silhouette XL, Interlude XL HRC, and Sonata XL suspension
systems (with a 5/16" shoulder height), use Tegular panels with
the panel face resting on the trim flange, and 5/8" concealed
tile – use AXTBC Connector Clip.
5.1 Attaching to Suspension System
Axiom Indirect Light Coves are installed before acoustical
or drywall suspension systems. Most acoustical and drywall
systems will attach directly to the light cove. There are several
options for the Axiom connector clip used to attach the
suspension system to the cove. Carefully review these options
based on the systems you are installing.
