Metalbest 4DT-WT Direct-Temp 4" x 6-5/8" Direct Vent Wall Thimble

4" x 6-5/8" Direct Vent Wall Thimble from Direct-Temp

This two-piece wall thimble easily slides together for installation on wall thicknesses of 4" to 7". This serves a dual purpose as both a heat shield and firestop.

Heavy duty centering brackets keep inner pipe centered and chamfered edges allow for easy slide-together assembly. The free-floating inner liner allows the pipe to expand and contract under high temperature, without creating gaps or stress points. The LockTab(r) is a unique design that allows for 360° rotation while securely locking the sections of pipe together with just a push of the tab.
