Information on material change to SL-17 Yoke

Below is copied an information bulletin received from Divex.

Change to Product Bulletin 2 of 2000: 3 Aug , 2000
(Revision of Bulletin 1 of 1999)

Subject: Material change to SL-17 Yoke
Products Affected: Yokes for all SuperLite 17 A/B and MK 21 Helmets.

DSI is replacing the existing fiberglass yoke (31), DSI Part Number 520-060, with a new yoke, DSI Part Number 520-117 (no price change). The new yoke is made of a durable black polyurethane, molded around a stainless steel core, and is slightly heavier than the fiberglass. This yoke will become standard equipment on all SuperLite 17 A/B & MK 21 helmets produced as of June 15, 1999.

The new yoke is fully retrofittable with the fiberglass unit it replaces and is readily retrofittable to all SL-17 A/B helmets. The only difference is that the three stainless washers, (DSI Part Number 530-530 – location number 30 on the exploded view), used on the fiberglass yoke hinge installation are not used on the polyurethane yoke hinge installation.

Old Part Number: 520-060

This fiberglass yoke will remain available as a special order spare part.

New Part Number: 520-117

Note: There is no change of part number for the neckclamp / yoke assembly, 505-008 which is also now standard with the new black polyurethane yoke. No Price Change.
