RIM HEIGHT ADJUSTERS
IPB6410/IPB6415 Center Strut Adapters
These adapter brackets are required when mounting a ZipCrank Manual Height Adjuster to
a ceiling mounted structure that currently mounts the backboard directly to the 6” or 6 ⁄”
diameter single center drop tube and not to the corners of the backboard. Specify whether
your drop tube is 6” diameter (18.9” circumference) or 6 ⁄” diameter (20.8” circumference)
and the left to right mounting pattern on the backboard you wish to install. These adapters
are sold in pairs and position the face of the backboard approximately 9 ½” from the forward
most surface of the 6” or 6 ⁄” drop pipe. Call for help selecting the right adapters.
ZipCrank™ Four Corner Mount Design
Designed to be installed between the backboard and the backboard support
structure, these height adjusters provide superior backboard rigidity when
compared to most center mount rim height adjuster devices. Available in either
manual or electric 110 volt models. Manual crank models can also be operated with
optional BA931 Cordless Winder. Electric models can be operated with the BA980EW
Portable Electric Wand or with any of the gym control options found on page 12.
The up and down movement is held rigid by means of two, 1” diameter polished
plated steel rods on each side of the height adjuster. All moving parts have grease
ttings for smooth operation. Other features include easy-to-read height indicator
labels, powder coated gray nish and ve-year limited warranty.
NOTE: Adding a ZipCrank height adjuster to existing structures will move the face of
the backboard 4¼” closer to the free throw line or more if your structure requires
the addition of Center Strut Adapters shown below.
BA980RS Manual adjuster ts structures with board mounting patterns common for 42” x 72”
corner mounted backboards (approx. 36” x 62”).
BA980RSE Electric adjuster ts structures with board mounting patterns common for 42” x 72”
corner mounted backboards (approx. 36” x 62”).
BA980RT Manual adjuster ts structures with board mounting patterns common for 48” x 72”
corner mounted backboards (approx. 42” x 62”).
BA980RTE Electric adjuster ts structures with board mounting patterns common for 48” x 72”
corner mounted backboards (approx. 42” x 62”).
BA980F Manual adjuster ts structures with board mounting patterns common for fan
shaped backboards and some other backboards with 20” x 35” backboard mounting
patterns.
BA980RS for 42” Short Rectangular Backboards
In most cases if your backboard is 42” tall and 72” wide and mounted to the structure in
the four upper and lower corners of the backboard, this model will typically bolt directly to
backboard and structure without any eld drilling. Typical backboard mounting pattern on
42” x 72” glass, steel, wood or berglass backboards is 36” top to bottom and approximately
62” (slotted or 2-hole pattern) left to right. Be aware that some 42” x 72” backboards have
other hole patterns, most notably, the 20” top to bottom and 35” left to right that is also
common on fan shaped backboards. If your backboard is not mounted to the structure in the
four corners, see IPB6410/IPB6415 adapters.
BA980RT for 48” Tall Rectangular Backboards
Same basic design as BA980RS above but designed to mount directly to most 48” high and
72” wide backboards that mount to the structure in the backboard corners. Typical mounting
pattern is 42” top to bottom and 62” left to right. Be aware that some 48” x 72” backboards
have a dierent mounting pattern. If your backboard is not mounted to the structure in the
corners, see IPB6410/IPB6415 adapters below.
BA980F for Fan Shaped and Fan Conversion Backboards
Use this height adjuster for all fan shaped backboards and any rectangular backboards that
have a typical fan hole mounting pattern that is 20” top to bottom and 35” left to right
(slotted or 2-hole pattern).

RIM HEIGHT ADJUSTERS
Electric Y-Frame
Center Mount Y-Frame Design
IPI Y-Frame height adjusters can be mounted to either 6” diameter (18.9
circumference) or 6 ⁄” diameter (20.8” circumference) center drop tubes.
Available in either manual operated or electric operated models, each unit
makes adjustments from ocial 10’ rim height to 8’ rim height quick and
easy. Available to adapt to any common backboard size including 42” x 72” or
48” x 72” rectangular or traditional fan shaped.
When raising and lowering, two 1⁄” galvanized tubular tracks ride in steel
guide tubes to provide smooth up and down operation. Easy to read rim
height labels insure proper height every time. Specify center drop tube size,
backboard type and manual or electric operation at time of order.
IPHA120YM Manual
The least expensive rim height adjuster. Rim is adjusted by means of a hand crank from
the oor. A ⁄” threaded acme lead screw and nut is rotated clockwise to raise goal
and counter clockwise to lower. Hand crank is included with each order. If ordering for
retrot, specify 6” or 6 ⁄” drop tube diameter and backboard type to insure proper
selection.
IPHA120YE Electric
Simplify raising and lowering goals with IPI electric height adjusters. This height
adjuster has similar features to IPHA120YM above but substitutes a 120 volt UL
approved linear actuator for the manual lead screw assembly. Linear actuator has
adjustable limit switches to automatically stop the goal at ocial 10’ height and at the
bottom goal height of 8’. Each electric height adjuster requires 110 volt power that can
be hardwired from the ceiling to allow operation with any of our wide variety of control
systems or can be operated with a portable wand that plugs into any 110 volt outlet to
eliminate the need to hardwire . See BA980EW below. If ordering for retrot, specify
6” or 6 ⁄” drop tube diameter and backboard type along with desired operator control
device (see page 12).
TR86 Youth Mini Goal
Easy Up™ is a great option to
reduce goal height to as low
as 6 ½’ for youth play without
permanently mounting height
adjusters that can only lower rim
to 8’. Lightweight, easy to install,
remove and store. Mounts to any
manufacturers rim without tools in
seconds. Moves backboard 2’ closer
to free throw line.
