Boldtbags Static Dry Sift 4 Screen Kit - 24" × 36"

Boldtbags Static Dry Sift 4 Screen Kit - 24" × 36" Inconsistent sift quality often comes down to screens that sag, shift, or lose tension mid-run — and that inconsistency shows up directly in your final yield. While some processors utilize a Boldtbags CO2 Shaker Kit for rapid initial separation, the Boldtbags Static Dry Sift 4 Screen Kit gives processors a precision-built four-screen stack in a 24" × 36" format, covering 75u, 149u, 165u, and 250u to progressively refine material from bulk separation down to finished-grade dry sift. Each screen is mounted on a food-grade powder-coated aluminum frame using food-grade glue, and stretched using a proprietary automatic stretching machine that ensures uniform tension across the entire working surface. That pre-stretched construction eliminates the slack and distortion common in lesser screens, so every pass delivers repeatable, grade-consistent output. Every screen in this kit is precision manufactured in the U.S.A., and a Certificate of Compliance is included. Whether you are using a Boldtbags Frozen Dry Sift Kief Box for smaller batches or processing at scale, the Boldtbags Static Dry Sift 4 Screen Kit gives you the full micron range and frame quality to produce clean, consistent dry sift from start to finish. Features 🔢4-Screen Micron Stack Includes 75u, 149u, 165u, and 250u screens to take material from bulk separation down to finished-grade dry sift in a single workflow. 📐Large 24" × 36" Format The generous working surface handles larger runs efficiently without requiring multiple passes to process the same batch volume. 🖼️Food-Grade Aluminum Frame Each screen is mounted on a powder-coated aluminum frame using food-grade glue — no off-gassing, no contamination risk at the frame joint. ⚙️Proprietary Pre-Stretched Mesh Screens are stretched using a proprietary automatic machine for uniform tension across the full working surface — no sagging, no inconsistent filtration. 🇺🇸Precision Manufactured in the U.S.A. Every screen in this kit is manufactured domestically to tight tolerances, with a Certificate of Compliance included for quality verification. ✅Certificate of Compliance Included Each kit ships with a Certificate of Compliance, giving commercial processors the documentation they need for quality assurance records.

Included Documentation Certificate of Compliance Frequently Asked Questions What micron sizes are included in this kit?+ This kit includes four screens: 75u, 149u, 165u, and 250u. Together they cover the full range of dry sift grading — from initial bulk separation at 250u down to finished-grade collection at 75u. What are the screen dimensions?+ Each screen in this kit measures 24" × 36", providing a large working surface suited for both small-batch hobbyist use and higher-volume production runs. What materials are used in the frame and mounting?+ Screens are mounted on a food-grade powder-coated aluminum frame using food-grade glue. Both the frame finish and the adhesive are selected specifically to eliminate contamination risk at the mounting point. How are the screens stretched?+ Boldtbags uses a proprietary automatic stretching machine to pre-tension each screen before mounting. This process ensures uniform tension across the entire working surface, which prevents sagging and produces consistent filtration pass after pass. Where are these screens manufactured?+ All screens in this kit are precision manufactured in the U.S.A. A Certificate of Compliance is included with each kit for quality documentation purposes. What is the Certificate of Compliance for?+ The Certificate of Compliance documents that the screens meet Boldtbags' manufacturing standards for food-grade materials and construction. It is particularly useful for commercial processors who maintain quality assurance records for their operation. Can these screens be used for both hobbyist and commercial production?+ Yes. The 24" × 36" format and four-screen micron stack make this kit practical at both scales. Hobbyists benefit from the complete grading range in a single purchase, while commercial processors appreciate the large working surface and compliance documentation.
