Review: Good Product. - great product. Would buy again. Review: Great upgrade for the price - Drawer slides worked as expected. I purchased these to replace existing slides at my house, which I believed to be the same model. Upon installation, I realized that some of the specs had changed since the previous ones were installed (8 years ago). Though the slides worked fine, the soft close feature long expired. I ended up having to clearance openings on the drawer for the runners about 1/8" on each side (which wasn't a big deal) making the installation slightly more annoying. Overall, I'm very satisfied as I no longer need to hear my family slam the drawer whenever something is thrown away! ## Features - Complete pair for face frame or frameless application - Elongated holes for depth adjustment & bottom mount holes - Full extension and soft closing - 100 lbs static load bearing capacity - Four-dimensional adjustment ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09ZT1TC8P | | Best Sellers Rank | #118,119 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #256 in Cabinet & Furniture Drawer Slides | | Brand | Blum | | Brand Name | Blum | | Color | brite zinc | | Customer Reviews | 4.8 out of 5 stars 137 Reviews | | Drawer Type | Under Mounted Slide | | Finish Type | Maple, Cherry, Quarter Sawn White Oak, Hickory, Rustic Hickory, Walnut, Gunstock Oak, Brown Maple, Red Oak, Gray Elm Finish Type Maple, Cherry, Quarter Sawn White Oak, Hickory, Rustic Hickory, Walnut, Gunstock Oak, Brown Maple, Red Oak, Gray Elm See more | | Finish Types | Maple, Cherry, Quarter Sawn White Oak, Hickory, Rustic Hickory, Walnut, Gunstock Oak, Brown Maple, Red Oak, Gray Elm | | Item Dimensions L x W x Thickness | 21.5"L x 2"W x 2"Th | | Item Weight | 6 Pounds | | Manufacturer | Blum | | Manufacturer Part Number | 563H5330B-45F42 | | Material | Metal | | Material Type | Metal | | Maximum Weight Capacity | 100 Pounds | | Model Number | 563H5330B-45F42 | | Mounting Type | Bottom Mount | | Number of Items | 2 | | Product Dimensions | 21.5"L x 2"W x 2"Th | | Unit Count | 2.0 Count | ## Product Details - **Color:** brite zinc - **Material:** Metal - **Brand:** Blum - **Product Dimensions:** 21.5"L x 2"W x 2"Th - **Finish Type:** Maple, Cherry, Quarter Sawn White Oak, Hickory, Rustic Hickory, Walnut, Gunstock Oak, Brown Maple, Red Oak, Gray Elm ## Images ![21 Inch Drawer Slide, Full Extension, Concealed, Undermount. 563H5330B with 100 Lbs.
