

XL: Stab Tee
ML: Hook Tee
HD: Heavy Duty
R: Retail – Designates that the product is made for retail sale and carries a UPC bar code so that it can be scanned by the piece
X: Designates that the product is PeakForm
SS = Stainless Steel
AL = All Aluminum
WA = White Aluminum
NA = Natural Aluminum
G90 = Higher Galvanized Coating used for exterior applications along with white aluminum capping
FEATURES:
“Stake-On” Clip





Has a “second stop” design which provides a tighter, secure connection (over 300 lbs. connection strength)
Excellent module control
Removable and reusable
Compatible with Prelude and Prelude Fire Guard Systems
Audible click when engaged
“Rotary Stitching”


Mechanically bonds the two layers of metal that form the web
Increases torsion strength and provides extra stability during installation
“Hot Dipped Galvanized”



Inhibits red rusting better and longer than electro-galvanized or painted systems
Gives a “shiny” metal finish vs. a dull finish look with electro-galvanized coating
Superior base metal coating that contains up to 10 times more zinc than electro-galvanized coating


ALL base metal, including the end detail, are coated with baked polyester paint for maximum corrosion resistance and structural
strength
G30 (standard product), G60 (high-humidity interior applications with aluminum capping) and G90 (outdoor applications)







Patented profile
Stronger, yet lighter weight due to shape of the profile and lighter gauge metal
Easier to cut and install – requires less pressure to insert into next piece
SuperLock clip for added security
Audible “click” assures a proper connection every time
Easy to remove and reuse – can be removed side-to-side versus end-to-end
NOTE: Prelude PeakForm main beams can only be used with other PeakForm main beams
“PeakForm” Main Beam (Prelude/Prelude Fire Guard/Suprafine)
Intermediate Vs. Heavy Duty:


Intermediate weight grid systems carry a minimum of 12 lbs. per lineal foot
Heavy-duty weight grid systems carry a minimum of 15 lbs. per lineal foot
Override vs. Butt Edge:


XL cross tee has an override and sits on top of flange of main runner
ML cross tee has a butt edge and butts up next to the flange of the main runner (does not sit on top of flange)
Expansion Joint:

When using a fire-rated main runner, UL Code requires an additional hanger wire be installed within 3 inches of the expansion joint
because it is the weakest part of the component
 Our competition, USG, only sells fire-rated main runners – which is an advantage to Armstrong (hanger wire and labor
savings)
 If a fire rating is not required, Armstrong can sell Prelude which saves money because of the price of the component and
the labor involved with installation of hanger wire
GENERAL ESTIMATING FOR GRID:


A full carton of 12’ mains covers approximately 1,000 square ft.
For every carton of 12’ mains, you need 2 cartons of 4’ tees; 2 cartons of 2’ tees (if using 2’x2’ tile)
EASY UP TRACK & CLIP SYSTEM


Metal track and clip system used to install direct-apply products
Easy Up clip also compatible with Prelude main runners and cross tees to install WoodHaven on a suspended grid system
DRYWALL GRID & FRAMING SYSTEMS



Grid systems to create flat, tray, soffit and curved drywall ceilings
Basement framing systems for walls and ceilings
Pre-engineered with rout locations to maintain precise, module spacing saving time and money
