PowerShell to assign permission to a folder (not copy inherited permissions)

In my previous post, I used PowerShell to change the permissions of a top level folder. In that script, I took the folder in question and copied the inherited permissions to it, and then I tinkered it to be what I wanted. I wanted to do something similar, but I wanted a set of permission that differed from the parent. Basically I wanted the folder to have unique permissions. Below is the function to do that:

function JBMURPHY-PERMS-ClientsFolderReBase {
    Param([parameter(Mandatory = $true)]$Path)
    $correctACLs = New-Object System.Security.AccessControl.DirectorySecurity
    $correctACLs.SetAccessRuleProtection($true,$true)
    $Rule_Admin = New-Object Security.AccessControl.FileSystemAccessRule("BUILTIN\Administrators",@("FullControl"),"ContainerInherit, ObjectInherit","None","Allow")
    $Rule_System = New-Object Security.AccessControl.FileSystemAccessRule("NT AUTHORITY\SYSTEM",@("FullControl"),"ContainerInherit, ObjectInherit","None","Allow")
    $Rule_Users1 = New-Object Security.AccessControl.FileSystemAccessRule("BUILTIN\Users",@("ReadAndExecute", "Synchronize"),"None","None","Allow")
    $Rule_Users2 = New-Object Security.AccessControl.FileSystemAccessRule("BUILTIN\Users",@("Modify, Synchronize"),"ContainerInherit, ObjectInherit","InheritOnly","Allow")
    $correctACLs.AddAccessRule($Rule_Admin)
    $correctACLs.AddAccessRule($Rule_System)
    $correctACLs.AddAccessRule($Rule_Users1)
    $correctACLs.AddAccessRule($Rule_Users2)
    write-host "Changing $Path"
    set-acl $path $correctACLs
}

In line 3 I create a new ACl, and in line 4, I set the cal to not inherit parent permissions.

Lines 4-8 are the specific permissions I want to apply (they are addressing the same issue I described here)

Lines 9-12 add the new perms to the new ACL, and line 14 set the ACL of the folder to the new ACL.

A little different want o go about this, as I created an ACL from the start.
