WALL OPENING PROTECTIVE MATERIALS (CLIV)
This category covers proprietary compositions which are used to maintain the hourly ratings of fire resistive walls
and partitions containing flush mounted devices such as outlet boxes, electrical cabinets and mechanical cabinets.
The Individual Classifications Indicate the specific applications and the method of installation for which the
materials have been evaluated.
The basic standard used to Investigate products in this category is ANSI /UL 263. 'Fire Tests of Building
Construction and Materials'.

Type MPP -45+ moldable putty pads for use with max 4 11/16 by 4 11/16 In. flush device UL Listed Metallic
Outlet Boxes in fire rated gypsum wallboard watt assemblies framed with min 3 -1/2 In. wide wood or steel
studs and constructed as specified In the Individual U300 or U400 Series Wall and Partition Designs in the Fire
Resistance Directory.
Type MPP -45+ moldable putty pads for use with max 4 by 3 -3/4 by 3 In. deep UL Listed Nonmetallic Outlet
Boxes manufactured by Carton, made of PVC and bearing a 2 hr rating under the Outlet Boxes and Fittings
Classified for Fire Resistance category in the Fire Resistance Directory. For use in fire rated gypsum wallboard
wall assemblies framed with min 3 -5/8 in. wide wood studs and constructed as specified in the individual U300
Series Wall Partition Desings in the Fire Resistance Directory.
Moldable putty pads are to be Installed to completely cover the exterior surfaces of the box within the stud
cavity with a ball of the putty material used to plug the end of each electrical metallic tube or conduit at Its
connection to the box. A min 1/8 in. thickness of putty material Is required on the exterior surfaces of flush
device boxes in 1 and 2 hr fire rated Wall and Partition Desing. When the moldable putty pad outlet box protective
material Is used as directed, the horizontal separation between outlet boxes on opposite sides of the wall may be
less than 24 in. provided that the outlet boxes are not installed back to back.
