06.01.2006 – Flexmaster USA Alpha-Numerical Number Changes
The following products did not change in design; we did make some very minor corrections to the catalog numbers.
Flexible Products/ Thermo Sleeve:
• Type 3, 4, 5, 6 and 8 are now preceded by “B” (i.e. Type 3B) the “B” denotes Black Polyethylene vapor barrier.
• Triple Lock TL-V changed to TL-B for Black Polyethylene vapor barrier.
• NI-65 changed to NI-55; this correlates with the core found in our Type 5B and Type 5M.
• TS (Thermo Sleeve) has been changed to TSB, “B” denotes Black Polyethylene vapor barrier.
Sheet Metal Products:
Our sheet metal fittings traditionally have a “D” included in the catalog number if it has a damper.
• “SL” with damper is now “SLD” (example SL-BO3 now SLD-BO3).

All On-Line Submittal Data Sheets have been updated to reflect these changes
