FS-ONE MAX intumescent firestop sealant
Hilti’s new intumescent firestop sealant FS-ONE MAX is an improved version of the company’s popular FS-ONE firestop sealant. The new sealant still embodies the reliable features of the original FS-ONE, but now provides for better handling and longer shelf life. Its “new W-rated, multi-purpose formulation means this highly versatile product can be used for even more common through-penetrations in a variety of base materials, including concrete, masonry, and drywall,” says the company. The sealant is easy to dispense and is available in multiple package types (tubes, foil packs and buckets) to meet a variety of project needs. The product’s 12-month shelf life from date of manufacture helps reduce the risk of expired inventory. Now ethylene glycol-free, the sealant’s low VOC content also makes it an environmentally safe formulation that is non-harmful when used as directed.

Large-format fire resistive wall box
FSR’s PWB-FR-450, a large format wall box, provides multiple infrastructure mounting solutions for larger interfaces or equipment behind a display, or in other custom applications. Fire-resistive material is integrated within the unit’s door assembly, providing 1 hour of protection. The rugged 14-gauge steel back box installs between wood or steel studs, leaving proper spacing for the door to mount flush with the wall’s surface. Connections and cables are hidden behind the cover for a neat, elegant look. Three prewired integrated AC outlets aid installation. Internal compartments have a three-fourths-inch KO and concentric KO that goes up to 1.5 inches in the box’s top and bottom for cable/conduit entry. A two-part vented cover provides convection cooling for internal components. One or all of the internal brackets can be removed for custom configurations. This box has also been designed to accommodate Crestron’s larger DM-RMC-4K-SCALER-C 4K scaler/room receiver. Hardware is included.
