The Hennes-Johnson Bulk Caulk Loader HJ315 fills bulk guns straight from a 5-gallon pail of roofing cement or caulk. Detail work is where most crews lose time, and loading individual cartridges is one of the biggest culprits. The HJ315 eliminates that step and lets your crew keep moving.
The HJ315 is compatible with standard bulk caulk guns and works with roofing cement, lap sealant, and similar pail-packaged materials. Commercial roofing contractors use it for counter-flashing, perimeter detail work, and penetration sealing where volume and speed matter. Built by Hennes-Johnson, the same manufacturer behind some of the most durable silicone and mastic sprayers in the industry.
West Side Supply and Rental carries the HJ315 for roofing contractors nationwide. Call us at 816-443-3004 with any questions.
