Updates to UL System No. W-L-3306 utilizing the EZP544WD Bracket
This system has been updated to include the option for the use of the EZP544WD in both pre and post gypsum board configurations. The EZ-Path® Series 44+ Dual Bank Multi-Gang Wall Bracket (Cat. No. EZP544WD) further expands on the cable capacity and density of our EZ-Path® Series 44+ Multi-Gang Wall Bracket (Cat. No. EZP544W). This bracket allows for up to 10 Series 44+ Devices to be installed, in 2 banks each consisting of up to 5 devices, while still fitting between standard 24 in. OC stud spacing. This increased density of devices provides a cable loading area of 68% of the wall space used, while competing solutions utilizing a similar amount of wall space only allow for a loading area of 36%. In other words, a single EZP544WD bracket fully populated with devices can accommodate up to 2,100 Cat6 Cables (OD of 0.236”).

 

UL System No. W-L-3459 utilizing the EZP644W & EZP644WD Bracket
This is a new system for using the EZP644W & EZP644WD brackets, these brackets are the direct result of feedback from the Data Center Community looking for solutions for even wider and deeper cable pathway designs. The EZ-Path® Series 44+ Six Gang and Twelve Gang Wall Brackets (Cat. No. EZP644W & EZP644WD respectively) provide unmatched cable capacity and density in wall penetrations, accommodating for cable trays of up to 24” wide loaded to 100% fill without issue. These two new brackets were designed for applications such as Data Centers where pathway cable density is paramount (Cat. No. EZP644WD) as well as for in congested ceiling spaces where wider, shorter trays are used over narrower, deep or multiple trays (Cat. No. EZP644W).When fully populated the EZP644W bracket can accommodate for 1,260 Cat6 Cables (OD of 0.236”) while the EZP644WD bracket can handle up to 2,520 Cat6 Cables (OD of 0.236”).

 

UL System No. W-L-3460 utilizing EZP544WV
This is a new system for using the EZP544WV vertical gang brackets. The EZ-Path® Series 44+ Multi-Gang Vertical Wall Bracket (Cat. No. EZP544WV) allows for ganging of 1-5 devices vertically up a wall cavity instead of horizontally across it. This new bracket provides the same density and capacity of cables as our existing EZ-Path® Series 44+ Multi-Gang Wall Bracket (Cat. No. EZP544W) while providing designers additional flexibility in orientation of their cabling pathway without sacrificing Fire-Ratings, Leakage Performance, or cable density.
