Roof Davits /
Tie Back Anchors

Roof davits and tie-back anchors are used during exterior building maintenance to the exterior façade of a structure, such as window washing, caulking and painting. These anchors are capable of withstanding an ultimate load of 5,000 lbs in any direction per Cal/OSHA Title 8, 3291 to allow for the suspension of scaffolds or Bosun chairs.

Our roof davits are trusted by building owners throughout California. We guide you through every step of the process from initial consultation to engineering and installation, all while ensuring you have the proper test documentation per Cal/OSHA Title 8 requirements.

F.A.Q.

When are roof davits required?

Buildings 36’ tall or 3 stories are required to have roof davits (tie-backs) unless you can achieve window washing and unscheduled maintenance from ground-based equipment. At 48’ or 4 stories, you must provide them regardless of ground-based equipment capability.

At minimum, they must be installed at intervals of 12’ on center around the building for unscheduled maintenance, and if used for window washing, must be specifically designed to accommodate the particular window washing activities.

Do we need an OPOS (operation procedure outline sheet)?
Not for unscheduled maintenance. For window washing activities, it depends on a few factors that would cause the building to require one: (1) the building does not have established window cleaning systems or procedures meeting the requirements specified in Articles 5 and 6; (2) the building has extreme architectural features which require the use of complex rigging or equipment; (3) or a building that uses rigging or equipment not covered by these orders. The quick answer is that an OPOS is needed when the building requires special types of cleaning procedures such as a Bosun chair.
How often do roof davits (tie-back anchors) need to be inspected and re-certified?

Each roof davit installation shall undergo a periodic inspection and test at least every 12 months by the equipment manufacturer, authorized representative, or other qualified person acceptable to the Division. All parts of the equipment, including related building support structures, shall be inspected, and where necessary, tested to determine to be in safe operating condition.

Are roof davits the same as fall protection anchors?

No. Roof davits are designed to have the capability of suspending scaffolding or personnel from the anchor to safely work on the face of a building. Rooftop fall protection anchors are designed to protect a worker from falling off the building.

Fall protection anchors are typically much smaller and have far less strength requirement. Roof davits must be capable of 5,000lbs in any direction while fall protection anchors must have an ultimate strength of 5,000lbs or meet a safety factor of two as a complete fall protection system.

Are roof anchors the same as roof davits?

Yes. Roof davits are sometimes also referred to as roof anchors, tie-back anchors, tiedowns, tie-offs, anchor rings, roof posts, 5,000lb anchors, and scaffold anchors.

Roof Davits and/or Tieback Anchors

When your commercial building requires cleaning, repairs, or maintenance, it’s your responsibility to ensure the workers stay safe. Roof davits, and/or tie-back anchors, are an important safety feature for construction or maintenance workers working on the exterior of any tall building.

Roof davits / tie-back anchors are used during maintenance to the external face of a building, such as window washing and painting. These anchors are capable of withstanding an ultimate load of 5,000 lbs in any direction per Cal/OSHA Title 8, 3291 to allow for the suspension of scaffolds or Bosun chairs.

Safety is the number one priority for workers performing above-ground operations. When workers step onto a suspended platform, it’s vital that safety systems work properly. Roof davits aren’t simply a good idea for these workers, they’re required by Cal/OSHA.

Most people don’t know much about roof davits, and that’s okay. Our experts know all the important details so the local employees who spend their days toiling above ground can get the job done right and get safely back on solid ground. Here are the essentials, in case you’d like to learn more.

Components of Roof Davit Systems

While there are several types of roof davits, they work much the same way and are created with the same basic components. There are four components that make up a roof davit system.

Davit Base

The base attaches permanently to the building’s roof as the main support for the arm and also the platform used by workers. Roof-rigged bases are larger, so they will have the strength to support the extending structure. Ground-rigged davits are designed differently with a smaller base, but they’re not suitable for all jobs.

Davit Arm

Davit arms are brackets that attach directly to the main platform. They mount in the connector socket when the platform is ready to be attached for a job. Davit arms are reinforced for additional strength and to withstand uneven weight distribution.
Unlike bases and sockets, davit arms don’t stay fixed to the building. They are mobile to allow flexible use in multiple places. This flexibility allows companies to save considerably since they don’t have to purchase arms for each base.

Adopter Sockets

The adopter socket is a connector made of galvanized steel. It’s designed to connect the base of the roof davit to the arm. Adopter sockets are generally permanent fixture that can either be exposed on the roof or embedded to be less noticeable. The adopter sockets you use will likely be decided by your building’s aesthetic and the type of roof davits you require.
There are three types of adopter sockets: embedded, flush mounted, and mobile.

Transport Handle and Wheel Assembly

Since davit arms aren’t permanently attached, they need a simple mode of transport. That’s where the transport handle and roller wheel assembly comes in. The transport handle and roller wheel assembly is the transportation kit used to carry davit arms to different installation sites as needed.

Most Common Roof Davits

Fall protection isn’t a one-size-fits-all product. Therefore, there are several types of roof davits available to fit the requirements and restrictions of the job at hand. The most commonly used types of roof davits are below.

Material Lifting

Every job requires tools and supplies which are often heavy and bulky. Material lifting davits are designed to carry supplies needed to complete a job up or down the building facade.

Personnel Lifting

Designed to carry people who are making repairs or maintaining the outside of a building. They may be used for transport to and from the roof or work on the side of the building, like window replacement.

Motor-Powered

The use of a motor allows these davits to offer greater control for the transport of heavy, bulky items. They’re often used during construction or major repairs to carry things like HVAC systems and equipment for maintenance.

Hand-Powered

While hand powered davits offer less control, they have their own advantages. They are easy to assemble and take apart, making them perfect for quick and/or light lifting jobs.

Ground-Rigged

Designed to provide lifting capability for jobs that don’t require work above the third floor, ground-rigged davits ascend from the ground rather than descend from the roof. They require less space than davits that are rigged from the roof.

Roof-Rigged

These davits require more roof space and have longer and taller arms than ground davits. This allows them to handle sizable platforms and work well with a variety of building types.
