System Number [HW-D-0846](https://files.stifirestop.com/1.%20System%20PDF%20Files%2F1.%20UL%20and%20cUL%20Systems%2Fhwd0846_dl.pdf) is a NEW head-of-wall joint system for 1 or 2 hr fire-rated gypsum walls abutting concrete floor assemblies.

**Features & Benefits**  
 •  Newly sized 8 in. (203 mm) high version of SpeedFlex® Joint Profile (Cat. No. SFJP80) and SpecSeal® AS200 Elastomeric Spray act as joint system  
 • Allows 100 % compression or extension of a 1-3/4 in. (44 mm) joint  
 • System accommodates a total displacement of 3-1/2 in. (89 mm)  
 • Industry leading movement capabilities for a “wet seal” system  
 • Competing systems with 100% compression or extension allowances are forced to rely on complicated track systems and installation of cumbersome wall cladding strips  
 • Perfect solution for projects specifying a large degree of movement
