Rose Dynescape 506630

Front Rear

Technical Details

I acquired my Rose Dynescape 506630 used on eBay from Barry Line in 2008. Barry acquired it from a sporting goods store that was going out of business.

This Rose Dynescape is 515 mm. tall, 240 mm. wide, 180 mm. thick, and weighs 15.7 kg. The Dynescape is an inertia reel descender that contains a 52 foot (16 m.) cable inside a plated steel case. The end of the cable is crimped to form an eye around a swivel, and the swivel has a hinged hook. The hook has a safety catch that helps prevent inadvertent opening. A rubber ball on the cable keeps the end of the cable from retracting inside the housing.

My Dynescape has many stickers and one riveted plaque. The plaque on the lower left front gives the serial number, "T10209B." The most important sticker on the front has the following text:

PART NUMBER:  506630





The other sticker on the front says "Rose Manufacturing Company," "Equipment Service Hotline," and "1-888-737-7339."

The rear cover has a logo with "ROSE," "TYPE," and "S.N." in raised relief. Neither the type nor serial number spaces contain entries. The back has one large and one small sticker. The large sticker is too wordy to justify reproducing here; basically it contains instructions for inspection, installation, and use. It also gives the devices specifications and the Rose Manufacturing Company address and telephone. The smaller sticker repeats the address and telephone information, and also states "Made in U.S.A." The operating specifications are worth noting here:

Working load: 75 to 310 lbs (34 to 141 kg)
Rate of descent: 6 ft. (2 m) per second
Cable length: 52 ft. (16 m)

There is also a caution sticker around the edge that gives 22 bullets of warnings.

The hook has a number of stampings, including several warnings and also some references to U.S. Patents #4,434,536 and #4,528,728 for snap hooks.


Although this descender is designed for industrial use, some rock climbers are using these or similar models for self-belayed top-roping. Although it is pricey, I can imagine a wealthy climber equipping her home climbing wall with one.
