Middle Atlantic LL-DWR/SR-BP Lever Lock Back Pan Bracket for DWR and SR Series
Overview
The Middle Atlantic LL-DWR/SR-BP is a steel back pan bracket engineered specifically for the DWR and SR rack series, designed to reduce installation time on equipment mounting tasks. If you're integrating Middle Atlantic rack solutions into a structured AV or security deployment, this bracket closes the gap between a bare rack frame and a finished, ready-to-populate rear bay — without the improvisation that wastes time on-site. The LL-DWR/SR-BP (often searched as LL DWR/SR BP) ships at 1 lb, keeping the overall rack build weight in check.
Middle Atlantic's Lever Lock accessory line targets exactly the kind of friction that slows down professional installations: mismatched hardware, loose-fitting panels, and back-panel assemblies that require extra hands or extra trips to the job box. This bracket is purpose-built to eliminate that friction for rack accessories deployments in the DWR and SR families.
Key Features
- DWR and SR Series Compatibility: Designed exclusively for Middle Atlantic DWR and SR base series racks — no guesswork about fit. Specify this bracket when your rack BOM calls for either series and you need rear bay coverage without sourcing a custom solution.
- Steel Construction: The bracket is fabricated from steel, giving it the rigidity expected in permanent commercial rack installations. Steel holds tolerances better than aluminum alternatives under thermal cycling in enclosed equipment rooms — relevant when the rack sits in a warm IDF closet running 24/7.
- Installation Time Savers: Middle Atlantic explicitly classifies the LL-DWR/SR-BP under its Installation Time Savers feature set. In practice this means the bracket is designed to drop in and lock without extended alignment work — a meaningful factor when you're commissioning multiple racks on the same site visit.
- Lever Lock Integration: Part of the LL (Lever Lock) accessory family, this back pan works within Middle Atlantic's broader modular rack mounting hardware ecosystem. Lever Lock components are designed to pair with each other, so if you're already specifying LL-series rails or panels, the LL-DWR/SR-BP stays consistent with that system.
- Low Shipping Weight (1 lb): At 1 lb (0.5 kg), this bracket adds negligible load to freight shipments. Order multiples without meaningfully impacting shipping costs — relevant when stocking hardware for multi-rack deployments across distributed sites.
Integration and Compatibility
The LL-DWR/SR-BP is engineered for Middle Atlantic's DWR (Deskwall Rack) and SR (Slim 5 Rack) series enclosures. Specify it alongside the matching rack frame when building out a complete enclosure. It is not a universal back pan — verify your base series before ordering. For guidance on matching rack components to your project requirements, review the rack systems selection guide.
Frequently Asked Questions
Q: Which rack series does the LL-DWR/SR-BP fit?
A: The LL-DWR/SR-BP is designed for Middle Atlantic's DWR and SR base series racks. Verify your rack series designation before ordering — it is not a universal fit for other Middle Atlantic families.
Q: What material is the LL-DWR/SR-BP made from?
A: Steel. This provides the rigidity needed for permanent commercial rack installations and holds tolerances under normal equipment room thermal conditions.
Q: How much does the LL-DWR/SR-BP weigh?
A: The shipping weight is 1 lb (0.5 kg). Actual product weight will be slightly less once packaging is removed.
Q: Is the LL-DWR/SR-BP part of a larger modular system?
A: Yes — it is part of Middle Atlantic's Lever Lock (LL) accessory line, designed to work with other LL-series rack components such as rails and panels within DWR and SR enclosures.
Q: Does this bracket reduce installation time?
A: Middle Atlantic classifies it under their Installation Time Savers feature set, meaning it is designed for faster alignment and engagement compared to standard back pan solutions requiring independent hardware alignment.
When I'm speccing out a DWR or SR rack build, the back pan is one of those components that gets overlooked until someone's on-site trying to terminate cables with no rear structure to work against. The LL-DWR/SR-BP solves exactly that — it's a steel back pan purpose-built for those two series, and at 1 lb it's not adding meaningful weight to the enclosure.
Technical Highlights:
- Series-Specific Fit: Designed exclusively for DWR and SR base series — eliminates the trial-and-error of testing generic panels against proprietary frame geometry.
- Steel Fabrication: Steel construction holds rack tolerances in enclosed equipment spaces where temperature variation would flex lighter materials over time.
- Lever Lock System Integration: Part of the LL accessory family — pairs cleanly with other LL-series components so the back pan doesn't become the weak link in an otherwise modular build.
Deployment Considerations:
- Confirm your rack's base series (DWR vs SR) before ordering — this bracket is not cross-compatible with other Middle Atlantic families, and the LL-DWR/SR-BP won't fit frames outside those two series.
- Evidence covers series fit, material, and weight only — installation torque specs, exact panel dimensions, and finish details are not confirmed in available documentation, so verify with Middle Atlantic's current datasheet for your specific rack configuration.
Best fit for integrators deploying multiple DWR or SR enclosures on a single site and looking to standardize rear bay hardware across all racks — the Installation Time Savers classification is a real differentiator when you're commissioning six racks in a day.
