Professional Grade 70 Transport Chains – Heavy-Duty Tie-Down Series

DOT/FMCSA Approved Carbon Steel Chains for Flatbed Hauling, Logging, and Heavy Machinery

OVERVIEW

Ensure maximum load security and regulatory compliance with our Professional Grade 70 Transport Chains. Engineered specifically for the rigorous demands of the heavy hauling industry, these high-tensile tie-downs are forged from heat-treated carbon steel, providing exceptional strength-to-weight ratios. Finished in a high-visibility gold chromate to resist rust and environmental corrosion, every chain is stamped at regular intervals to meet strict DOT and FMCSA inspection requirements. Available in versatile pre-cut lengths with clevis grab hooks, or as continuous-length bulk pails for custom fleet outfitting, this series is the definitive standard for towing, logging, and heavy machinery transport.

SYSTEM HIGHLIGHTS

  • DOT & FMCSA Compliant: Every chain is permanently stamped every foot with the Grade 70 identifier, ensuring immediate traceable load rating compliance during highway weigh station inspections.

  • Heat-Treated Carbon Steel: Forged and heat-treated to withstand extreme tension, abrasive wear, and high-impact shock loads without snapping or deforming.

  • Gold Chromate Defense Finish: The premium dichromate plating provides a highly visible yellow/gold finish that actively resists oxidation, road salt, and job site moisture.

  • Multi-Gauge Versatility: The matrix spans from standard 7.9 mm (5/16") to massive 15.9 mm (5/8") thicknesses, allowing operators to match chain strength to their specific Working Load Limit (WLL) requirements.

  • Bulk & Pre-Cut Configurations: Choose between ready-to-deploy 6.1 m to 9.1 m (20 ft to 30 ft) assemblies or high-volume continuous 18.3 m to 27.4 m (60 ft to 90 ft) bulk pails for shop fabrication.

Hit or miss
Size: Medium, Style: Beef, Size: Medium, Style: Beef
I’ve purchased this item multiple times. Twice now, I got duds. Within minutes of opening the package, the ball was destroyed. The other times, it lasted months! I don’t know how to explain it.

Still squeaking after all these days!
Size: Jumbo, Style: Beef
My power chewer GSPs usually wreck all "tough" toys in less than an hour, especially if they squeak. These seem pricey but I can say it's held up really well. After about three weeks, it's still hanging in there! The stripes are worn off but the squeaker still squeaks and that's what it's all about.

Long lasting scent and has not been destroyed by my heavy chewer.
Size: Jumbo, Style: Bacon
My medium puppy loves this ball. She already has the smaller size but appears to enjoy the challenge of catching the large one. An added benefit is it's easier for me to win it back when we fight (play fighting) for it. The scent really lasts. I've had the smaller version for a few months and the scent is still there. Does it really smell like bacon? Not to my nose but the puppy thinks it's awesome. The ball itself is really tough. The pup can destroy a tennis ball in a day. Except for a few teeth marks these balls are holding together great.

Worth every penny—my beagle is obsessed
Size: Medium, Style: Cheddar Cheese, Size: Medium, Style: Cheddar Cheese
No dog toy is indestructible if you have a hound or a pit. I happen to have a combination of both. This toy is the best $12 you could possibly spend for a dog that likes to “kill” their toys. The only reason I’m buying more is because I keep losing them. My dog is a rescue. She’s half beagle, a quarter boxer, and a quarter pit bull. She’s a tiny fire-cracker and I lover her to pieces. And she loves tennis balls to pieces. Literally. She adores tennis balls, squeaky toys, and food. She will absolutely try to surgically extract the squeaker from any toy she gets because she has a high prey-drive. These balls last usually at least a week before she manages to dislodge the squeaker or puncture the squeaking mechanism, but I still have one I got about six months ago that has the paint worn off and it still squeaks. This ball literally has everything. It squeaks, it bounces pretty high, it looks like a real tennis ball so my girl recognizes them as “toy” immediately, and they smell good. These balls in particular last forever. I got her a can of regular tennis balls and she had them in four pieces within 10 minutes or less, which is not healthy for her because she likes to eat the pieces. For this dog toy, I have never seen her crack it. She’s pushed the squeaker inside of exactly one of them so far, and it stayed inside the ball. Much safer than a toy that she can possibly ingest. The toys come in several colors, but it’s not just to make them look cute and colorful. The colors correspond to flavors, as each of the balls has a different scent. I’ve sniffed them and noticed there’s a mild food smell beneath the rubber scent. I can tell that dogs really do get a kick out of the “flavors.” I’ve taken these to the dog park and all the dogs want the Playology tennis ball, even if we have other generic balls flying around. My dog even has favorites. We have a muscle-head pit bull/staffy mix at the park who is a giant meat-ball. He got his hands on one of these and he wasn’t even able to break it open for at least 20 minutes of deliberate chewing. My girl’s favorite “flavor” for a long time was beef (the red one). The blue “peanut butter” flavor is the easiest one to find in stores. She was obsessed with a purple one for a while, apparently it was bacon flavor. I couldn’t find that one! I saw that Amazon has an orange “cheese” flavor and knew she’d love it. She’s obsessed. I really wanted to leave this review to convince people to invest in this product. Your dog will be so happy, and this company made something great. I’m worried because I went on their website yesterday and they had only one or two colors available. I don’t want them to stop making this amazing toy. I hope they don’t lose business because their product is TOO durable!! If they make more flavors, or maybe make some multi-dog (tug ropes?) or similar, I’ll definitely continue to be a customer. Please keep making these awesome tennis balls!

Not Squeakable for Mini/Toy Aussies
Size: Medium (VALUE 2-Pack), Style: Chicken
Very durable and good squeaker. However, too large and hard for my Mini Aussies to squeak. My Aussies love their squeaky toys, unfortunately not this one.
