RTUD4B Ratcheting Take-Up Device
The RTUD ratcheting take-up device is a cost-effective shrinkage compensation solution for continuous rod systems. The RTUD is now code-listed for use with rod systems to ensure highly reliable performance in a device that allows for unlimited shrinkage. Once the RTUD is installed, a series of internal threaded wedges enable the device to ratchet down the rod as the wood structure shrinks, but engage the rod in the reverse direction when under tensile loading. Continuous engagement is maintained on the rod at all times by the take-up device, enabling the rod system to perform as designed from the time of installation.
Maintains rod-system tightness, allowing it to perform as designed
Pass-through design provides unlimited shrinkage compensation
Available for 1/2", 5/8" and 3/4" diameter threaded rod
Fastens easily to the wood plate with the BPRTUD bearing plate and (2) 8dx1 1/2" nails (minimum) or (2) #9x1 1/2" Strong-Drive SD Connector screws (not included)
1.33-degree rod offset (1 3/4" max) allowed per floor
Very minimal force required to allow rod to pass through take-up device to mitigate rod buckling during wood shrinkage
RTUD—ASTM A732; BPRTUD—3 Gauge
RTUD—Corrosion-resistant finish; BPRTUD—None
The RTUD3 or RTUD4 must be installed on top of the BPRTUD3-4 bearing plate and fastened through the bearing plate to the wood top plates or bottom plate with (2) 8dx1 1/2" min. nails or (2) #9x1 1/2" Strong-Drive SD Connector screws.
