Parallel Beam-to-Beam Clamps
Join two beams in a straight line without drilling or welding. The bolt can be removed to insert threaded rod.
Zinc-plated iron clamps have mild corrosion resistance. Galvanized iron clamps have better corrosion resistance than zinc-plated iron clamps.

Clamping U-Bolts
Also known as muffler clamps, these U-bolts have a rounded mounting plate that fully surrounds pipe, conduit, and tubing for a secure fit. Stronger than routing clamps and hangers, U-bolts support heavy pipe, tube, and conduit from ceilings, walls, and poles.
Zinc-plated steel U-bolts have good corrosion resistance in most environments.
U-bolts with four nuts allow you to secure the U-bolt from the top and the bottom.

Hoist Rings—For Lifting
Designed for angular lifting, hoist rings resist stresses that would bend or break an eyebolt. They have a lifting ring that pivots 180° front to back and a base that swivels 360° to compensate for pitch, roll, and sway when lifting heavy or unbalanced loads. Install the base of the hoist ring flush to the mounting surface and tighten to the recommended torque that is stamped on the ring. Torque wrenches are sold separately.
Machined hoist rings have a smooth finish to protect slings and hooks from damage and excess wear during lifting.
Black-oxide steel hoist rings have mild corrosion resistance.
Nickel-plated steel hoist rings are more corrosion resistant than black-oxide steel hoist rings.
17-4 PH stainless steel hoist rings are more corrosion resistant than steel hoist rings.
316 stainless steel hoist rings are the most corrosion resistant.
High-visibility hoist rings are fluorescent green, so they’re easy to distinguish from other hardware when attached to equipment being lifted.
Hoist rings that are CE marked meet European safety standards.
Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the hoist ring can lift is significantly reduced. For example, when lifting a 1,000 lb. load at a 45° angle, you must choose a hoist ring with a capacity of at least 1,400 lbs. Do not use at an angle less than 30°.
Warning: Never use to lift people or items over people.

Side-Mount Hoist Rings—For Lifting
Choose these hoist rings when you need to lift your load from the side. Designed for angular lifting, hoist rings resist stresses that would bend or break an eyebolt. They have a lifting ring that pivots 180° front to back and a base that swivels 360° to compensate for pitch, roll, and sway when lifting heavy or unbalanced loads. Install the base of the hoist ring flush to the mounting surface and tighten to the recommended torque that is stamped on the ring. Torque wrenches are sold separately.
D-shape hoist rings have a wider end than triangle hoists, so it’s easier to attach webbing and large hooks.
Triangle hoist rings have a narrow end to keep chain in place.
Black-oxide steel hoist rings have mild corrosion resistance.
Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the hoist ring can lift is significantly reduced. For example, when lifting a 1,000 lb. load at a 45° angle, you must choose a hoist ring with a capacity of at least 1,400 lbs. Do not use at an angle less than 30°.
Warning: Never use to lift people or items over people.

Swivel-Under-Load Hoist Rings—For Lifting
The ball bearing on these hoist rings makes it easy to rotate your load even after it’s suspended. For unbalanced or heavy loads, the base also swivels to compensate for pitch, roll, and sway. Their lifting ring pivots 180° front to back. Ideal for angular lifting, these hoist rings withstand stresses that bend or break eyebolts.
Install the base of these hoist rings flush to your mounting surface. Use a torque wrench to tighten to the recommended torque stamped on the ring.

Hoist Ring Assortments—For Lifting
Keep on hand all the parts needed to assemble custom hoist rings. Ideal for angular lifting, these hoist rings will withstand stresses that bend or break eyebolts. The base of these hoist rings will swivel 360° to compensate for pitch, roll, and sway when lifting heavy or unbalanced loads. The shackle will pivot 180° front to back. All parts have a black oxide finish for mild corrosion resistance.
Install the base of these hoist rings flush to your mounting surface. Use a torque wrench to tighten to the recommended torque stamped on the ring.

Quick-Release Hoist Rings—For Lifting
Easily slip these hoist rings in and out of threaded holes by pushing the button to retract their threads. Install them flush to your mounting surface. Ideal for angular lifting, these hoist rings withstand stresses that break or bend eyebolts.
All are CE marked, so they meet European safety standards.
The ring on 180° pivot hoist rings moves from front to back. Their base does not swivel for added stability.
180° pivot and 360° swivel hoist rings not only have a ring that moves from front to back, but their base also swivels to handle pitch, roll, and sway when lifting heavy or unbalanced loads.
Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the hoist ring can lift is significantly reduced. For example, when lifting a 1,000 lb. load at a 45° angle, you must choose a hoist ring with a capacity of at least 1,400 lbs. Do not use at an angle less than 30°.
