The two workhorse EMS / rescue litters, the classic canvas-on-pole litter and the modern folding aluminum stretcher, overlap heavily in mission but split sharply on folded volume, weight, and rated load.
Junkin's JSA-501-NA canvas pole stretcher pairs 1-1/4 in anodized aluminum poles with an 18 oz vinyl cover, runs 87 in open, and weighs 14 lb; the same maker's JSA-603 easy-fold aluminum frame, no canvas bed, weighs 9 lb and folds to 36.5 in [S2]. For scene-to-ambulance and tactical use, folding pole litters cover a 6-11 kg band versus 3-5 kg for roll-up plastic and under 1 kg for soft poleless designs [S4].
What each design actually is
The canvas pole stretcher is the US military / NATO pattern: two long aluminum or hardwood poles joined by a canvas or vinyl-coated nylon bed, often with shaped hardwood handles [S2][S9]. It is rigid, repairable in the field by re-stapling canvas, and rides in vehicle brackets or a hard case; the JSA-610 break-apart pole stretcher pulls into two halves and folds to 45 in for stowage [S2].
The folding aluminum stretcher is a hinged aluminum frame with a fabric or PVC deck, designed to fold lengthwise or in an X-pattern; aluminum alloy dominates because it is rust-resistant and light, while the deck is usually PVC-coated fabric, Oxford cloth, or synthetic leather for fluid and flame resistance [S5]. Single-fold models hinge once at center; duo-fold or break-apart variants hinge twice to reach the 41 in x 7 in x 3.5 in storage envelope cited in current product literature [S1].
Weight, dimensions, and load rating compared
Across the Junkin catalog, the JSA-603 easy-fold plain stretcher is 9 lb at 74 in open / 36.5 in folded; the JSA-602 adds 4 in wheels and support posts at 13 lb; the JSA-604 with 5-position adjustable back rest is 20 lb; and the JSA-501-NA canvas pole stretcher sits at 14 lb and 87 in open [S2]. The JSA-305 litter support stands pair with any standard litter and are rated to 700 lb at 12 lb folded weight [S2].
Folding stretcher weight typically spans 6-14 lb, while most aluminum and steel frames are rated 350-500 lb; the LINE2 Design Portable Patient Transport Unit pushes to 1500 lb with extra carry handles for bariatric use [S1]. The Tactical SKED lists at $742 versus the Alfa Charlie MOLLE Rescue Stretcher at 3.2 kg and roughly €250, a useful reference point for the soft / roll-up sibling category [S4].
Material, finish, and deck options
Anodized aluminum tubing is the industry default for both pole and folding frames; the 6000-series alloys balance strength, weight, and corrosion resistance, and anodizing adds a hard oxide layer for institutional cleaning regimes, a topic covered in our aluminum alloy reference. Vinyl-coated nylon at roughly 18 oz is the typical pole-stretcher deck and is fluid-resistant, while folding-stretcher decks lean toward PVC-coated fabric, Oxford cloth, or synthetic leather for flame-retardant and anti-bacterial performance [S2][S5].
For a heavier load or rough terrain, mild steel frames still appear on some single-fold stretchers, but the weight penalty versus aluminum is the usual reason buyers switch [S5]. Hardwood handles on the classic pole design (for example, the JSA-501-NA and the easy-fold pole-stretcher kit) give a positive grip when carriers wear gloves or work in rain [S2][S9]. FDA approval is cited on common US folding models, which matters for hospital and mortuary buyers; the Propac L2200 aluminum folding stretcher is one example [S8].
Use-case fit: which one to choose
For ambulance, fire, and rescue vehicles that already have racks and need a flat, rigid bed that locks into brackets, the canvas pole litter or its break-apart variant (JSA-610) is still the default, with its 87 in open length, hardwood handles, and field-repairable deck [S2]. For confined-space work, stairways, or facilities that need compact wall-mounted stowage, the folding aluminum stretcher wins on folded volume and often on weight, especially the 9 lb JSA-603 [S1][S2].
For tactical and point-of-injury movement where a kit is carried on the person, the roll-up or soft poleless category takes over at 3-5 kg and under 1 kg respectively, well below the 6-11 kg folding pole litter band [S4]. A typical kit is one rigid roll-up plus one soft litter per operator, with folding pole litters reserved for vehicles, a deployment pattern documented in current tactical-procurement guidance [S4]. For mortuary and funeral-home transport, a folding aluminum stretcher inside the 350-500 lb rated band covers routine work, with bariatric units reserved for 1000+ lb cases [S1].
Standards, compliance, and procurement checks
Standard folding stretchers typically list FDA approval, a 350-500 lb rated load, and 6-14 lb carry weight, and most fold to roughly 41 in x 7 in x 3.5 in for stowage in a vehicle, closet, or wall bracket [S1][S2][S8]. The military / NATO canvas pole litter follows a common dimensional pattern so it locks into standard vehicle and helicopter stanchions [S4].
Specifiers should confirm deck fire-rating claims (PVC-coated fabric, Oxford cloth, synthetic leather are commonly listed as flame-retardant), handle type (fixed vs foldable, anti-slip grip), and presence of patient safety straps before purchase [S5]. For lift-height and operator ergonomics in industrial first-aid rooms, the JSA-305 litter support stands raise any standard litter to treatment height at a 700 lb capacity, a common pairing for both pole and folding frames [S2]. Buyers looking at overall aluminum stretcher options across ladders, panels, and window / door categories can cross-reference our aluminum stretcher and aluminum ladder pages for context on alloy selection and load rating.
Limitations and failure modes
Canvas pole stretchers expose the fabric to wear at fold points and staples; field repair is possible by re-stapling, but heavy patient loads combined with wet canvas will sag and stretch over time [S2][S3]. Folding aluminum stretchers concentrate stress at hinge pins, and repeated folding cycles eventually wear the locking mechanism, which is why duo-fold units specify 350-500 lb rather than the 1500 lb bariatric ratings on rigid frames [S1].
Soft poleless litters need four to six carriers, which is unrealistic in a two-person EMS crew, and roll-up plastic designs lose rigidity once a casualty exceeds roughly 180 kg unless the unit is rated higher, as the Alfa Charlie MOLLE is at 180 kg [S4]. Cold-weather brittleness, vertical-lift instability, and suspected spinal injury all rule out flexible designs and push the choice back to a folding pole litter or scoop stretcher [S4]. Aerial work platform wind speed and personal eyewash vs ANSI Z358.1 are unrelated items, but the same rule of pairing a rated primary with a compliant secondary applies here: pair a folding pole litter with a rated support stand and a vehicle rack that matches its dimensional pattern.
Track the next purchase decision by weighing folded length, weight, and rated load against the 9 lb / 36.5 in / 350 lb baseline of the JSA-603, and by verifying FDA listing or common NATO-pattern dimensions on the quote sheet; expect 2026 EMS catalogs to keep this split, pole canvas for vehicles, folding aluminum for compact stowage, and roll-up / soft for the point of injury.
