The main difference between Blum Tandem and Salice Progressa is in their synchronization and application versatility. Salice Progressa uses a precision-engineered rack-and-pinion system to keep both drawer slides perfectly synchronized, ensuring smooth, even movement under heavy loads. It also offers a 120-pound weight capacity with Italian-made components. In contrast, Blum Tandem excels in installation flexibility, offering a robust 4-way adjustment system and a wide range of mounting options tailored for both face frame and frameless cabinets.
Key Differences Between Blum Tandem and Salice Progressa
When it comes to drawer slides, the details matter. In our testing, we found that Blum Tandem and Salice Progressa represent two similar, yet distinct, approaches to drawer hardware. Each system has its own strengths that become clear when you install and use them daily.
| Feature / Spec | Blum TANDEM + BLUMOTION | Salice Progressa |
|---|---|---|
| Soft-Close Mechanism | Yes – BLUMOTION integrated for quiet self-close. | Yes – Smove integrated for gentle soft-close. |
| Push-to-Open Option | Not built-in; requires Tip-On add-on or use Blum’s Movento line for push-open. | Yes – Progressa+ Push slides include integrated push-open (no handles needed). Optional synchronizer for wide drawers. |
| Load Capacity | ~100 lb static (75–90 lb dynamic per length) on standard slides. Heavy-duty Blum (Movento) for higher loads. | 120 lb on standard Progressa; up to 170 lb static on Progressa+ heavy-duty models (formerly F70). Suited for large pantry drawers, etc. |
| Drawer Side Thickness | 1/2″–5/8″ standard (563H series); Blum offers a variant (563F) for 3/4″ thick drawer sides. | 1/2″–5/8″ standard models; 3/4″ thick drawer sides supported on heavy-duty Progressa+. |
| Drawer Lengths Available | Standard lengths 9″, 12″, 15″, 18″, 21″ (in 3″ increments). Some Blum slides available up to ~30″ in special lines or Movento. | Available in common lengths 15″ (381 mm) through 30″ (762 mm) for full extension. Covers small drawers to very deep drawers. |
| Adjustment Features | 4-way adjust: Height via locking clips (+3 mm), side-to-side (with optional clips), depth (elongated holes), tilt (tool-free adjust on slide). Precise alignment for inset or flush drawers. | 3-way adjust: Tool-free side ±1.5 mm, depth ±3 mm, height +2.5 mm, plus optional tilt +3 mm. Front locking clips available in standard or narrow versions for different drawer types. |
| Installation | Uses front locking devices that clip the drawer onto slides (several types: standard or side-adjustable). Rear brackets are available for face-frame cabinets. Many templates and jigs from Blum ease installation. | Uses front clips/locking devices (standard and narrow versions) to latch the drawer onto the slide. Rear mounting sockets for face-frame cabinets (sold as F70 brackets) ensure proper slide support. Salice provides drilling templates to speed installation. |
| Build & Finish | Zinc-coated steel, concealed undermount design. Made in USA (Blum’s NC plant) for US market slides. Smooth dual-spring dampers for soft-close. | Steel slides with bright zinc plating. Made in Italy with precision rack-and-pinion synchronization for ultra-smooth travel. Robust build, though slightly softer steel per some installers (anecdotal). |
| Standout Benefits | Proven reliability – industry favorite for high-end cabinetry. Exceptionally smooth rolling action on polymer rollers, and wide range of accessories (e.g. Servo-Drive electric open, Orga-Line dividers) for customization. Massive supply and support network. | High performance – very stable even for wide drawers, thanks to a synchronized “S-Drive” rack-and-pinion mechanism that keeps drawer sides moving evenly. Integrated push-to-open option is perfect for modern no-hardware looks. Excels with heavy loads or large drawers. |
| Typical Price (pair) | ~$20 for a 18–21″ pair (e.g. SKU 563H4570B), plus ~$1–$3 total for two Blum locking devices. Bulk discounts for contractors are common. | ~$22 for an 18″ pair (e.g. SKU G5U6S457XXF6). Includes the slides only (front clips ~$1 each sold separately). Often sold in sets of 10 or more for volume pricing. |
🏋️ Strength & Synchronization: Salice Progressa Leads on Load and Control
If your priority is high-capacity, high-performance drawer motion, Salice Progressa Undermount Drawer Slides deliver unmatched support.
- Static load capacity reaches 120 lb (170 lb on Progressa+).
- Built-in rack-and-pinion system keeps both slides perfectly synchronized, preventing racking or misalignment on wide drawers.
- Smove soft-close tech provides consistent damping throughout the entire close cycle—smooth, strong, and whisper-quiet.
In contrast, Blum Tandem drawer slides handle 100 lb static and 90 lb dynamic loads. They use an adaptive roller carriage system that self-adjusts to drawer weight for a gentle close. It’s quieter and more than capable for residential needs—but less rigid under heavier loads.
🛠 Installation & Adjustability: Blum Tandem Is More Forgiving
For installers or shops working across different cabinet styles, Blum Tandem undermount drawer slides offer maximum flexibility.
- Tool-free 4-way adjustments: height (+3mm), side (+/-1.5mm), depth (+/-4.5mm), and tilt (+5mm).
- Wide compatibility with face frame cabinets using rear brackets and plug-in sockets.
- Narrow, inset, and bottom-mount options available in the Tandem lineup.
Salice Progressa, while precise, offers 3-way adjustment plus optional tilt (+3mm). But it requires blocking for face frame installations, which increases prep and install time.
🏗 Cabinet Compatibility: Frameless vs Face Frame
- Frameless Cabinets: Both systems work well and install cleanly.
- Face Frame Cabinets: Blum Tandem is optimized with accessory brackets and sockets. Salice Progressa needs exact blocking behind the frame to create a flush mounting surface—adding steps, but delivering rigidity.
🧰 Build Quality & Origin
- Salice Progressa: 100% made in Italy using bright zinc-plated steel. It meets ANSI/BHMA Grade 1 and is WI certified for commercial-grade use.
- Blum Tandem: Made in the U.S. (North Carolina) with European components. It also meets ANSI/BHMA Grade 1 and ISO 9001 standards.
Both are built to last and rigorously tested—your decision should be based on features, not quality.
