Inside the Sumner 783801 Eventer Lift: 800 Lbs, 20 Feet, Built for the Stage

When you're setting up for a live show, you don't have time to fight with equipment that wasn't built for the environment. The Sumner 783801 Eventer Lift is designed specifically for theatrical and entertainment applications. It reaches just over 20 feet, holds 800 lbs at the load center, and does it all with black anodized aluminum masts that are built to disappear into stage environments. 

Here's a full breakdown of everything you need to know.

The Sumner Eventer Series was created with staging and entertainment professionals in mind. Traditional material lifts work, but they weren't designed for the demands of live production — quick assembly and breakdown between shows, the need to look good (or invisible) on stage, and the requirement to reliably lift speaker arrays and lighting trusses night after night.

The Eventer addresses all of that. The series comes in three sizes — 16 ft, 20 ft, and 25 ft — and the 783801 is the 20-foot model. It hits the sweet spot for most live production setups: enough height for mid-size venues and concert stages, with the highest load capacity in the series at 800 lbs.

Sumner is part of the SFE Group of brands, the same company behind B&B Sumner, Mathey Dearman, and other industrial equipment lines. The Eventer line is their purpose-built entertainment product, developed with input from staging professionals who use this type of equipment on actual productions.

This is the feature that separates the Eventer from a standard material lift. The telescoping masts are finished in black anodized aluminum — the same way pro audio gear and stage hardware is often finished. The result is a lift that visually recedes into a dark stage environment instead of standing out like a painted yellow or silver construction lift. For theatrical productions where aesthetics matter, that's not a minor detail.

The anodizing also adds a layer of corrosion resistance and surface hardness to the aluminum, which holds up well in the touring and rental market where equipment gets used hard, loaded and unloaded repeatedly, and transported from venue to venue.

The Eventer 20's forks are reversible, which adds versatility in tight backstage or wing spaces. When you flip the forks to the reverse position, you get additional lift height in situations where you're working close to a wall or structure and need every inch of reach you can get. It's a small mechanical detail, but it makes a real difference in cramped production environments.

Stage floors, load-in dock areas, and outdoor venue surfaces are rarely perfectly flat. The Eventer 20 includes built-in leveling pads to compensate for uneven surfaces and ensure the lift stays stable under load. This isn't just a convenience feature — it's a safety requirement when you're lifting speaker arrays or lighting rigs overhead near people.

At 27.5 inches long and 23 inches wide when stowed, the Eventer 20 is designed to fit in a typical production trailer. The operating footprint is 77.25 by 75 inches — roughly 6.5 by 6.25 feet — which is manageable in most venue settings. The lift is built for quick assembly and breakdown, which matters on a tight turnaround between shows. You're not spending an hour assembling a lift when load-in is already compressed.

Two accessories are designed specifically for the Eventer 20 and 25 models:

The Hook Block Kit (HBK20, part number 783766) expands what you can lift and rig with the Eventer 20. The Sound Array Bar (SAB20, part number 784060) is designed for flying speaker arrays and AV equipment — one of the most common production applications for this lift. Both accessories are sold separately through Sumner's distributor network.

The Eventer series gives you three height options, and the right one depends on your venue and what you're lifting:

The Eventer 20 (783801) sits in the middle of the lineup and carries the highest load capacity of the three at 800 lbs. If you're choosing between models, the 20 is the most versatile option for indoor venues and mid-size touring productions. The 16-foot model works for smaller venues where you don't need the height. The 25-foot model extends your reach for large-scale outdoor productions and high-ceiling venues, but at a slightly lower load capacity of 650 lbs.

The Sumner 783801 Eventer Lift is built for a specific professional — someone working in live production, theatrical staging, or the AV and entertainment industry. If you're regularly setting up speaker arrays, flying lighting trusses, or rigging production gear in venues and theaters, the Eventer 20 is purpose-built for that work.

It's also a staple of the rental and staging market. Companies that provide lift equipment for concerts, corporate events, and theatrical productions can rely on the Eventer's durability and fast setup for high-turnover rental inventory. The anodized finish and professional-grade construction hold up well under the repeated use that rental equipment demands.

This isn't a general construction material lift. If you need a lift for drywall, HVAC equipment, or mechanical work, Sumner makes other products better suited for those applications — the Series 2100 Contractor Lift, the Series 2000 Material Lift, and others. The Eventer line is theatrical and entertainment specific.

The Sumner 783801 Eventer Lift 20 is exactly what it says it is — a professional-grade lift engineered for live production and theatrical environments. It reaches 20 feet, holds 800 lbs, assembles quickly, and does it with the kind of low-profile, black anodized construction that production professionals expect. If your work involves flying speaker arrays, lighting trusses, or AV gear in venues and on stages, the Eventer 20 is worth a close look.
