I agree with riggerbob but I also think that kind of rigging work should not be on the market. I hope that all other rigs that the specific rigger Ass I&R are not the same - he better check his past rigging. I would like to add more information: #4 metal links are not the best item for Ty.7 & 13 webbing & when they are in use they should be set with long side to riser & short side to lines & the barrel facing the center. Silicone bumper are MANDATORY on PD reserves with #4 links & Fabric bumpers on #5 links. Both methods are in the PD new manual, they keeps the lines centered on the link, keeps the link centered in the riser, eliminates the line loop to move under the barrel & protects the slider grommets from nicks & burrs. The bumpres of both kinds MUST be hand tacked to the links!!! I have seen reserves that the rigger removed the Silicone bumpres or left them without hand tacking. Since we have the SR-1 Reserve Slinks there is no reason to order a new reserve with metal links BUT they should be set according to the instructions & the 1/8" Ty.3 Yellow tab shuold be hand tacked to the riser to insure the SR-1 will not turn outside. The SR-1 are better & stronger then the metal links when properlt installed. (PD new manual) If a rigger change from metal links to SR-1 he must insure that the slider grommets are clean & free from ANY nicks & burrs. Using Loctite & match mark the link is mandatory in the PD old manual & it is in the new manual page 32 above "Slinks" match marl is not in the new manual but is good to match mark the links. *** Loctite & match mark are not a replacement for links inspection at the 120 cycle. Derek, I would not leave the #4 links without bumpers just add the PD bumpers or change to SR-1 Derek, you should call the rigger & EDUCATE him, Rigger ticket is a ticket to learn ALWAYS !!! TIP: When moving links in/out from risers COVER the threads & the nut with GAFFER'S/DUCK TAPE to eliminate any damage to the webbing from the sharp edges of Stainless Steel links, REMOVE after setting or moving out. RIGGING IS AN ART TO BE DONE WITH LOVE & PRIDE. I WISH ALL OF US SAFE RIGGING. HAPPY NEW YEAR FOR 2004
