The ascent plates are designed to provide just enough floatation in soft snow to take the suffering out of long climbs. By allowing the front points of the crampon to engage the snow normally they still allow the crampon to provide an element of security. THESE ARE NOT TRACTION DEVICES. They are designed for use in soft snow, if the snow is firm enough that the plates are not providing float we recommend that they be removed and carried until soft snow is again encountered. They are designed to assist with front pointing, as in kicking steps straight up. They are not intended for side-hilling on firm snow or other hard surfaces, the side rails are for stiffening purposes and are not intended to be an edge for side-hilling. Ascent Plates are not designed to be used in rocky terrain, hard or variable snow or ice.
The plates are designed to fit a wide variety of crampons and as such there may appear to be some play, especially in the width of the toe bale cut out with some crampons. When properly installed on a boot with a rubber (Vibram) sole the plate will not move regardless of apparent gaps in the fit. If you experience movement let us know and we will review your fit.
It is strongly recommended to rub some ski wax on the underside of the plates prior to use if wet snow or “balling” conditions are expected
- To set sizing of the plate-first set your crampon to your boot. Your normal size setting of your crampon should not need to be adjusted to install the plate, but if you prefer to run your crampons tightly you might need to loosen them a touch. Place the crampon on a flat surface and set the forward portion of the ascent plate on the crampon with the crampon toe bale in the forward cut out. See Figure 1. It is better to have a little space here then to have the bale tight to the plate. See Figure 2.
- Next set the back portion of the Ascent Plate on the heel portion of the crampon with the heel bale leaning forward over the front portion. Line up the crampon heel ‘nubs’ with the holes in the back plate. See Figure 3.
- Line up the small holes in the back plate with the holes in the front plate according to the position relative to the crampon. Note: that it is better to have the plates slightly small rather then pushing tightly against the toe bale. See Figure 3.
- Ensure the small plate sits on top of the larger portion and that the screws go in from the top. We recommend 3 per side, but two per side (4 per plate) can be used if you are counting grams. Ensure all fasteners are secure but do not over tighten.
- To install the crampon/plate on the boot-first push the heel bale thru the large rectangular hole in the centre of the Ascent Plate. Holding the crampon by the heel bale, line up the heel ‘nubs’ with the smaller holes in the Ascent Plate. With your other hand grab the toe bale and engage the toe of the boot into the toe bale. Then attach the heel bale as you normally would.
