CONCEALED CEILING SYSTEMS
INTRODUCTION
Whether you’re looking to direct fix or fully suspend your
plasterboard ceiling, the Rondo KEY-LOCK®Concealed
Suspended Ceiling System is designed to produce a high-
quality structure for a flawless, flush or featured finish.
The KEY-LOCK®system can also be used as a framework to
line virtually any existing wall or substrate.
It’s our most popular and superior ceiling system as it is
available for fire-rated, bulkhead, seismic and acoustic
designs, as well as having the strength to hold multiple
layers of plasterboard.
SUITABLE FOR
• Flush plasterboard ceilings
• Direct Fix or Fully Suspended applications
• Non-Fire Rated systems
• Fire Rated systems
• Acoustic Systems available (by design)
• Seismic Systems available (by design)
SPECIAL FEATURES
• Able to be designed for external use, for example
External Soffits
• Base material engineered from G2 BlueScope Steel for
strength and reliability
• Primary and secondary profiles available in custom
lengths or radiusses
WHY USE KEY-LOCK®
The components within the system have been specially
designed so that they simply snap into sections, without
mechanical tools being required. This means it’s easy to
install and speeds up time on site.
Top Cross Rail and Furring Channel sections have rolled
edges to make them safer to handle and with our state-
of-the-art manufacturing processes, we can also produce
these profiles in custom lengths or radiuses for vaulted and
curved ceilings.
Our KEY-LOCK®Ceiling System can also be installed with
our Acoustic Mounts to improve airborne sound and impact
sound transmitted between floors, which is particularly
important in multi-residential projects.

SUSPENDED CEILING INSTALLATION
For ceilings with more than 200mm suspension depth, a fully suspended system should be installed.
MASONRY WALL INSTALLATION
Rondo Furring Channels and adjustable clips are the ideal combination for battening out irregular walls,
ready for the fixing of building boards.
1. INSTALL CLIPS
Fix the adjustable BetaGrip®Clips to the masonry wall as figure 8 inset using either “knock-in” anchors or plugs
and screws. For timber framed wall use suitable screws. (See note on fixing alternatives for BetaGrip®Clips).
2. ATTACH FURRING CHANNEL
The BetaGrip®Clip has ‘notches’ to accept the furring channel, these are spaced approx 5mm apart.
Selecting the appropriate notch and using a rolling action clip the 129 or 308 Furring Channel into place.
Check the first Furring Channel for plumb and straightness and using this as a guide install the remaining
Furring Channels. For more minute adjustment of the clips for plumb etc., gently tap the prongs of the clip with
a hammer to adjust.
3. FIX PLASTERBOARD
Screw fix plasterboard, tape and set joints and sand off as lining manufacturers recommendations.
1. Fix Rondo 140 Wall Track (or 142 Wall Track if using the
308) around the perimeter of the ceiling
2. Secure hanger clips at a 1200mm x 1200mm grid pattern
ensuring the first Top Cross Rail is located within
200mm of abutting walls. If using multiple layers of
plasterboard consult the Rondo Professional Design
Manual.
3. Cut 121 Suspension Rod to required length and slide
into hanger clip tabs. Refer Figure 6.
4. Slide 2534 Clip onto the other end of the rod.
5. Secure 127 Top Cross Rail to the 2534 Clips with a
twisting action. Fit 139 Joiner Clips to Furring Channel
and then click into Top Cross Rail* firmly. Ensure 139
Clip engages in both sides: “click-clack”.
6. Secure Furring Channel to Top Cross Rail at a maximum
of 600mm apart or at appropriate spacings for your
lining choice, ensuring 5–10mm clearance is left
between end of Furring Channel and wall.
7. Framing can be leveled by adjusting the 2534 Clip by
squeezing tabs together.
8. See illustrations below for fixing and bracing details.
NOTE:
Distance between hangers supporting TCR = span of TCR
