6" Square Parabolic Trim
Flush Mount
Kurt Versen’s flush mount fixtures eliminate overlapping
flanges and lock into the ceiling for a unique, finished
appearance. A clean, uncluttered ceiling emphasizes the
attention to detail, enhancing the impact of the interior
environment. It is a factory installed option with a proven
installation technique.

Optics and Applications
Standard fixture is for BT-15 lamps. It can be factory
ordered or field converted for use with A-19 lamps. The
primary reflector produces a smooth, medium wide
pattern for general use.
Design Features
The square trim has parabolic contours for maximum
brightness control. Aperture appearance from all normal
viewing angles is soft and luminous. Flush mount design
resists cracking and chipping by mechanically fastening
fixture to drywall. To simplify installation, three adjustment
mechanisms adapt the fixture to ceiling conditions.
Adjustable mounting rails fit different support systems
and accommodate ceiling thicknesses from 3/8" to 7/8".
Maximum extension is 26". Top or bottom service.
Representative illustration.
Finish
Trims are anodized Softglow® clear with optional colors
available. Housing and structural parts are painted optical
matte black to suppress stray light leaks. Steel parts are
phosphate conditioned for corrosion resistance before
painting, then baked for superior adhesion and durability.
General
Fixture is pre-wired and thermally protected, UL and
C-UL listed for damp location and eight wire 75°C branch
circuit wiring. Union made IBEW.

Graphite x .75, Titanium x .75, Bronze x .70, Black x .70.
3 Datachart spacing is rounded off to the nearest foot.
4 Datachart degree headings measure one side from nadir. Diameter data includes
both sides. Therefore the 10° column value describes a 20° pattern diameter at the
work plane 30" above the floor. Footcandle values are at the diameter edge.
