Overview


History

History

Boris Rogelja founded Single Rope Technique Equipment (SRTE) in 1980. Capital Safety Group acquired SRTE in 2011 and their devices started showing DBI-SALA, Capital Safety, and/or Rollgliss™ markings. 3M acquired the Capital Safety Group in 2015 and the Single Rope Technique Equipment markings disappeared.

Technical Details

I acquired my Single Rope Technique Equipment BP1 from Raven Products at the 1990 NSS Convention.

The Single Rope Technique Equipment BP1 is a milled from aluminum plate and soft anodized. Mine is 61 mm. long, 61 mm. wide, 10 mm. high, and weighs 50 g. It has two slots that are 29 mm. long and 14 mm. wide.

This plate is stamped "S.R.T."

Comments

The Single Rope Technique Equipment BP1 is a normal milled double-rope "Sticht" plate. The plate is not identical to the BPS plate with the spring removed: it does not have the turned notch and the holes are not threaded.

Technical Details

I acquired my Single Rope Technique Equipment BPS from Raven Products at the 1990 NSS Convention.

The BPS is 61 mm. long, 61 mm. wide, 46 mm. high, and weighs 89 g. It has two slots that are 30 mm. long. Two Phillips head screws hold the spring in a notch turned into the lower corner of the plate.

The top of this plate is stamped "S.R.T."

Comments

The Single Rope Technique Equipment BPS is one of many round "Sticht" plates with springs. This table compares the ones in my collection. Colored shading (not white) in the "Belayer" column indicates different brand plates with particularly similar plate designs, excluding markings and finish.

The spring helps the plate release under load, helping the belayer. I prefer having the spring. Unfortunately, the springs have a tremendous capacity for tangling with other equipment on a climber's rack. If you can't find a way to prevent this - and I've tried - you will hete the spring as I do.

Sticht Plates came in many variations.Some had one slot, some had two. Some slots were sized for 9 mm. rope, some for 11 mm. My preference is for two-slot plates since they are lighter and more versatile. Choose one that matches the ropes that you will be using. My first Sticht Plate had one 11 mm. and one 9 mm. slot. One could use the same slot for both, and get different performance, but I like the different size slots. I'm often climbed with an 11 mm.lead line and a 9 mm.haul line, so this arrangement suited me well. It was s a good choice for most situations other than rappelling on double 11 mm. lines.

All of the plates listed in the table have considerable wear margin. The Cassin #221.02 has a particularly thick hard anodized finish. I slightly prefer the hard anodized GAB plates, but don't see a large advantage over any other anodized plate, or even the bare plates. I dislike the painted plates.

There are several methods used to attach the spring to the plate. They all seem to be equally effective, but the ones using a side groove seem more robust than the ones using bottom grooves.

Most of the Salewa plates have spring brackets. They hold the spring in the compressed position for carrying.. Sometimes these are effective, but more often, I find them inadequate for their task.

The Single Rope Technique Equipment BPS is the only one without a hole for a keeper sling. I like having a keeper and having a hole to attach it instead of tying to the spring is nice. I would drill a hole in the BPS plate if I were going to use it much.

Many plates have a shallow groove across the top and bottom surfaces. The grooves don't seem to do much, in my opinion.
