No other product combines performance and ease of use as well as adds protection to deck joists and helps increase longevity. The G-Tape 3040BK Series provides the ultimate flashing performance with unmatched contractor friendly features. The AAMA 7-11 Level 3 Class A rating means the 3040BK tape meets the highest standards for hot and cold performance and does so without the need for any additional primer. It is lighter weight than butyl or rubberized asphalt flashings and outperforms these products by significant margins. Although the tape is permanent, it can be removed from face to face adhesive contact cleanly with no loss of performance during the application (meaning, if you accidentally fold a piece onto itself while removing the backer, you can still peel it apart). Review: Works well - Works great, very sticky, not a bad price for how much you get. Just as good as zip tape Review: The best flashing tape. - This tape is the best, it’s pricy but worth it. Sticks really well to anything and if it sticks to itself you can pull it apart. I used it for support posts at the ground level and it looks great goes on easy if it lasts half as long as they say it’s the bomb. ## Features - Perfect Flashing for Windows, Doors, & Deck Beams - Hand Tearing-Straight and Easy, Great Performance and Ease of Use - Waterproof, All-Weather Usage (-40°F to +200°F) - Highly Weather/UV Resistant, Permanent Adhesion - Cleanly Removes from Face-to-Face Adhesive Contact ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08267D91F | | Adhesive Format | Tape | | Adhesive Location | tape | | Adhesive Material | Acrylic | | Adhesive Side Count | 1 | | Best Sellers Rank | #116,012 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #56 in Roof Flashings | | Brand | Alpha Professional Tools | | Brand Name | Alpha Professional Tools | | Color | black | | Compatible Material | Wood | | Configuration | Size (2" x 65', 4" x 65', 6" x 65', 9" x 65', 12" x 65') | | Customer Reviews | 4.8 out of 5 stars 134 Reviews | | Item Resistance | Weather, UV, Water | | Item Weight | 0.69 kg | | Manufacturer | Alpha Professional Tools | | Material | Acrylic | | Material Type | Acrylic | | Model | GT3040BK04 | | Number of Items | 1 | | Number of Packs | 1 | | Other Special Features of the Product | Waterproof | | Part Number | GT3040BK04 | | Recommended Uses For Product | Indoor, Outdoor | | Size Name | 2" x 65', 4" x 65', 6" x 65', 9" x 65', 12" x 65' | | Special Feature | Waterproof | | Surface Recommendation | Wood | | UPC | 749173560835 | | Unit Count | 65 Feet | | Upper Temperature Rating | 200 °F | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Alpha Professional Tools - **Color:** black - **Material:** Acrylic - **Number of Items:** 1 - **Recommended Uses For Product:** Outdoor, Indoor ## Images ![G-Tape - Acrylic Flashing 4" x 65' Nichigo G-Tape GT3040BK04 - Image 1](https://m.media-amazon.com/images/I/31kA2IcLkkL.jpg) ![G-Tape - Acrylic Flashing 4" x 65' Nichigo G-Tape GT3040BK04 - Image 2](https://m.media-amazon.com/images/I/61ZDGM78nQL.jpg) ![G-Tape - Acrylic Flashing 4" x 65' Nichigo G-Tape GT3040BK04 - Image 3](https://m.media-amazon.com/images/I/41KOqi8T-YL.jpg) ![G-Tape - Acrylic Flashing 4" x 65' Nichigo G-Tape GT3040BK04 - Image 4](https://m.media-amazon.com/images/I/51qt+ll6pQL.jpg) ![G-Tape - Acrylic Flashing 4" x 65' Nichigo G-Tape GT3040BK04 - Image 5](https://m.media-amazon.com/images/I/51dMdFfnmuL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by K***F on April 20, 2026* Works great, very sticky, not a bad price for how much you get.
