We have been in the Building Maintenance industry for over 30 years, caulking high rise buildings and warehouse tilt ups using a variety of different products, including pre-formed silicone/urethane strips from the five major manufacturers. All of which are applied the same way.
Typical installation includes measuring and marking or applying masking tape to either side of the failed caulk joint to aid in width control and clean up. Considering every joint is a different width and wall detail, excessive time and money is spent on preparation, driving increased labor costs. A necessary process, yet I knew there had to be a more efficient way.
And so, the breakthrough solution - Dual Nozzle Systems for B-Line Sausage/Bulk Guns:
Dual-Bead (S) 1.5" & 2"
Dual-Bead Pro (S) Adjustable
These unique nozzle designs were created to accelerate the installation of pre-formed silicone/urethane strip products. Standard installation includes measuring the width of the joint, applying two beads at the exact distance apart and bonding the appropriately sized strip to those beads.
"Dual-Bead (S)" applies both beads of sealant/adhesive at the same time at 1.5" or 2" spacing. (It will also work on inside, outside corners and recessed joints).
"Dual-Bead Pro (S)" applies both beads of sealant/adhesive at the same time, can accommodate any width spacing up to 7" (with custom DBP angle adapters) and can be adjusted to accommodate any change in wall details, (including inside and outside corners), without having to remove the nozzle from the B-line sausage/bulk gun to do so. Simply set your width, lock in that spacing (with custom DBP locking nuts) and get to work.
"Dual-Bead (S)" and "Dual-Bead Pro (S)" can also switch effortlessly from a double nozzle to a single nozzle (with custom DB cap) and back again, by simply capping off one of the nozzles. These nozzles dramatically cut down on measuring time and reduce waste as the material is applied exactly where it is required.
We have been using these designs for several years on many different types of installations from bonding metal channels to walls, aluminum window headers to concrete, and expansion joint installations. The results have been an astonishing reduction in application times of 40% to 60%. That said, we are aware there are double bead nozzles on the market, but none are as versatile as the "Dual-Bead (S)" and adjustable like the "Dual-Bead Pro (S)".
